Email Marketing Myths to be on Guard for in 2025
In the ever-evolving realm of growth marketing, email should continue to remain a constant for businesses seeking to connect with their audience. However, amidst the plethora of information circulating, several myths about email marketing persist. Let us debunk 5 common misperceptions about email marketing that should be put to rest in 2025.
Email marketing is dead
This myth about email marketing is a popular one stemming from most probably, the perception that people are generally overloaded with promotional emails that they barely glance at. The reality is that when email marketing doesn’t work, it’s often because of the strategy, not the channel.
If your business’s email marketing strategy, however, isn’t delivering on expectations, conduct an audit and look at the following:
Your email marketing goals
Your email marketing campaigns
Your subscriber lists
Your send day and time
Your content and whether it fits what your customers need and how they process information
Sending too many emails kills email marketing efforts
When it comes to email marketing myths, it’s easy to believe that sending too many emails can ruin your email marketing campaign. What tends to happen, in reality, is that businesses go too far and spam users with emails that offer little value. Your company, however, can send frequent emails successfully if you ensure they provide value.
An e-commerce store offering a holiday sale, for instance, will likely benefit from sending multiple emails promoting the sale. Those emails remind shoppers about the offer and provide them with quick access to the sale.
How often you send emails depends on a multitude of factors
Industry
Email goals
Subscribers
Products or services
The availability of past business data on email send frequency and what works best
What is your audience looking to get from emails?
There is a right time of the day or day of the week to send emails
Search for the best day to send emails, and even Google will reveal this email marketing myth. The search engine compiles results that credit various days of the week as the best day, including:
Tuesday
Thursday
Saturday
Almost all base their recommendations on different studies and data points — and that’s fantastic. The problem is that these recommendations become facts for businesses getting started with email marketing.
While you can use Tuesday, Thursday, or another recommended day as your starting point, you want to test different days. Your business, industry, product or service, subscriber, and email content are unique. What you’re offering and who you’re offering it to may result in a top-performing send day that doesn’t match the general and generic best practices for email marketing.
That’s why it’s critical to test your send days and use your data to determine the best send day for your business. If you don’t test, you’ll never know, which can hold back your entire email marketing strategy.
The same holds for the time of day that you send out emails. Experimenting with your send times can help your company achieve the best engagement rates, as well as get the most value from your different email campaigns, whether they are designed as being for promotions, lead nurturing, or client retention. Use the industry’s recommended time, 4 p.m., as a baseline for your test effort, but do not be fixed on it.
Short Subject Lines Are Essential for Effective Email Marketing
Your subject line is your gateway to getting subscribers to open your email and act on your offer inside. While most studies point to 41 characters (or seven words) as the optimal subject line length, many mention that your optimal subject line will depend on factors related to your business, like your brand, products or services, audience, and more.
Again, similar to the myth about the best day to send out emails, you want to test. Test different lengths, whether by word or character count, for your emails and see what works best. This is where AB testing, where you test 2 different subject lines to 2 different subscriber subsets, comes into play. A/B testing can help you uncover the ideal length for your subject lines. What's more, you might also discover words, phrases, or angles that work well with your subscribers, which can lead to more opens, clicks, and conversions across your email marketing campaign.
People Just Do Not Read Emails Anymore
It's a common misconception that people don't read emails anymore.
The reality however is that email marketing remains one of the most effective ways for businesses to connect with their audience.
Research by Campaign Monitor shows that:
Over 58% of consumers check their emails every morning
More than 80% of smartphone users regularly use their device's email app
That being said, you must ensure your emails are relevant and engaging enough for your subscribers.
Sending generic or irrelevant content with flashy subject lines won’t cut it anymore. Personalization is key. Messages need to be tailored specifically for every subscriber on your list.
You Need a Huge Email List to Succeed
Many believe that a massive mailing list is crucial to email marketing success
However, this isn't true.
Engagement matters far more in email marketing. Even with a large list, reaching uninterested people won't help you succeed.
In contrast, an engaged small audience who regularly interacts with your emails will likely see better results than someone with an unengaged huge list.
Key Drivers of Success for Email Marketing in 2025
As we pivot further into 2025, the landscape of email marketing is evolving at a breakneck speed. Staying abreast of these changes is not just an option but a necessity for businesses aiming to thrive in the competitive digital space. In a realm where consumer preferences and technological advancements are constantly shifting, understanding key drivers in terms of getting the most out of your email marketing efforts is paramount. Let us look at 10 such factors for email marketing success.
1) Personalization:
Many overlook personalization in email marketing, believing it's not worth the extra effort.
However, personalized emails have a 29% higher open rate than non-personalized ones.
Understanding your audience and tailoring messages accordingly improves engagement rates while increasing customer loyalty and retention.
Quick Tips for Effective Email Personalization:
Use recipient names in subject lines and greetings
Segment lists based on demographics or behavior patterns
Send targeted content based on previous purchases or interests
Use dynamic content blocks that change depending on who is receiving them
2) Mobile Optimization
Over 70% of email opens occur on mobile devices, making it imperative to optimize emails for smartphones and tablets.
Mobile optimization involves designing emails that are easy to view and navigate on smaller screens with touch-enabled interfaces.
This includes:
Larger fonts
Shorter subject lines
Simplified layouts
Clear CTAs
Responsive design that adjusts automatically based on screen size
Reducing image file sizes for faster loading times
By optimizing your emails for mobile devices, you can:
Improve user experience
Increase engagement
Boost conversion rates
Enhance brand perception
Gain a competitive advantage
3) Developing a Clear Email Marketing Strategy
An effective email marketing strategy starts with aligning to your overall business goals and objectives. Common goals include increasing sales, generating leads, driving website traffic, building brand awareness, driving prospects through the purchase process, and retaining customers, and encouraging repeat purchases. With clear goals in mind, you can shape your strategy to optimize emails accordingly.
The key to this is identifying your target audience. Ideally, you'll have customer data to segment your lists, such as demographics, purchase history, interests, and engagement levels to ensure your emails are personalized to the greatest possible degree.
Determine what types of emails you'll send, such as promotional campaigns, transactional confirmations, newsletters, and product notifications, among others. Find the right balance between marketing, informational, and operational communications based on your objectives.
Finally, establish key performance indicators (KPIs) to track how your strategy is progressing. Useful baseline email marketing metrics include open rate, click-through rate, conversion rate, unsubscribe rate, deliverability, list growth, engagement levels, and ROI.
4) Building Your Email List
Building a quality email list is one of the most important steps in developing an effective email marketing strategy. Your list serves as the foundation for all of your email campaigns, so you'll want to focus on growing your list with engaged subscribers who want to receive your emails.
There are several key tactics for building your email list:
Collect Customer Contact Info
- Ask customers to join your list during the checkout process, or include a sign-up form or checkbox on your website. Make it easy for visitors to subscribe.
- Collect email addresses in person at events, trade shows, or your brick-and-mortar location if you have one.
- Add a pop-up or banner inviting visitors to join your list. But don't make it too intrusive.
- Offer a lead magnet or freebie in exchange for an email address. This provides an incentive to subscribe.
Use Opt-In Forms and Checkboxes
- Always use double opt-in signup forms. This verifies the email address and ensures subscribers want to be on your list.
- Use checkboxes allowing customers to select topics or categories they're interested in. This allows you to segment your list.
Offer Incentives for Joining Your List
- Lead magnets like ebooks, coupons, or free trials encourage sign-ups. Offer something of value in exchange for an email address.
- Hold contests and sweepstakes for subscribers only. Special offers increase sign-ups.
- Alert visitors to exclusive deals, early or private access to sales, and subscriber-only content.
Segment and Organize Contacts
- Group contacts by interests, demographics, purchase history, etc. Then target campaigns accordingly.
- Tag past customers and use automation to send them unique offers. Identify loyal buyers.
- Import contacts from CRM systems, events, or past purchases. Add relevant tags to each.
Building a segmented list of engaged subscribers ensures your future email campaigns will reach the right audiences with relevant content and offers. Invest time upfront to collect quality leads interested in your brand.
5) Email List Management
Managing your email list is crucial for successful email marketing. Here are some tips for proper email list management:
Maintain accurate and current data. Keep your list updated by allowing subscribers to update their preferences and information. Perform regular list hygiene by removing hard bounces and inactive subscribers.
Grow your list over time. Focus on building your list through lead generation. Offer incentives like discounts or content offers in exchange for emails. Make sign-up forms prominent.
Follow anti-spam laws and regulations. Honor unsubscribe requests immediately. Don't purchase email lists or use tactics considered spam. Stay up-to-date on regulations like GDPR.
Proper email list management takes continuous effort but pays off through higher deliverability, open rates, and conversions.
6) Creating Effective Email Content
Creating compelling and relevant email content is key to keeping subscribers engaged and driving conversions from your email campaigns. Here are some best practices for effective email content creation:
Personalize Your Subject Lines and Messages
Personalization can dramatically increase open and click-through rates. Include the recipient's first name, mention their company or location, or reference past behaviors in subject lines. Tailor content and messaging to subscriber segments whenever possible. Tools like mail merge can help to automate personalization at scale.
Keep Content Relevant, Concise, and Scannable
Only send emails highly relevant to each subscriber. Get to the point quickly and use shorter paragraphs, bullet points, and lists for easy mobile reading. Emails should be scannable at a glance to maximize engagement.
Include Images, Infographics, and Videos
Visual content makes emails stand out and drives more engagement. Relevant images reinforce messaging while infographics neatly present data and videos add a multimedia element. However, visual content does not just focus on images. Font size and style, for instance, can play a huge role in helping to ensure that your emails are presented in a more aesthetically pleasing fashion. The key is to ensure a balance of text and images and optimize visuals for email rendering.
Write Compelling Calls-to-Action
Effective emails guide the reader to take action. Maintain a clear CTA focus and place buttons for easy access. Match CTAs to the stage of the customer journey, promotions or campaigns. Test different CTA variations (e.g. wording, color, size) to determine what resonates best with your audience.
7) Email Design Best Practices
A well-designed email newsletter enhances engagement and drives action. Consider these best practices for email design:
Use Mobile-Friendly Responsive Templates
With the majority of emails now opened on mobile, having a responsive design is essential. Your template should detect the device screen size and adjust its layout accordingly. Text should resize without overlap, calls-to-action should be prominent, and horizontal scrolling should be avoided.
Responsive templates also provide the benefit of a consistent experience and branding across devices. Test your emails to ensure proper rendering on desktop, tablet, and mobile.
Maintain Clear Branding and Messaging
Every email you send represents your brand. Include your logo, color scheme, fonts, and tone to strengthen brand recognition.
Again, in line with the previous point about mobile optimization, consistency is key. Headers, footers, color blocks, image sizes, and placements all should avoid unnecessary variations between campaigns.
Just as important is to reinforce key messages and value propositions throughout your email content and design.
Use Simple Layouts and Formatting
Email clients filter out complicated coding and rendering. Stick to a simple linear layout with sections, minimal formatting, and basic table structures.
Prioritize the most important content at the top. Break up long sections of text with headers, lists, or images.
Limit styling to bold, italic, underline, and highlight color. Generally, it is considered best practice to try to use font sizes between 10 and 18 points.
Maintain a Consistent Structure
Having a consistent template structure trains subscribers to look for key content in predictable locations.
For example, hero images and headlines at the top, followed by a brief intro paragraph, sections for featured content, key product details, closing text, and a clear call-to-action at the bottom.
This helps guide the reader through your content efficiently. Avoid unpredictability or complicated non-linear layouts.
With a focus on responsive design, strong branding, simplicity, and consistency, you can create engaging email newsletters that are clear and make your content stand out. Test regularly and refine based on your CTR and conversion rate metrics.
8) Timing and Frequency Considerations
Finding the right cadence for your email marketing is crucial for maximizing open and click-through rates. You want to send frequently enough to stay top of mind, but not so often that you overwhelm or annoy subscribers.
Test Different Days and Times
Run A/B tests to see when your audience is most engaged. Weekends tend to have lower open rates, while early morning or mid-day on weekdays often perform better. You can also experiment with sending at different times of the day to determine if your subscribers prefer morning, afternoon, or evening. Track open and click rates to identify the optimal timing.
Avoid Oversaturating Subscribers
Too many emails in a short period can often lead to fatigue and disengagement. Spacing out your messages gives subscribers sufficient time to fully digest and absorb each email. As a general rule, no more than one commercial email per day. For retail/promotional content, 2-5 emails per week is typical. With educational/informational content you can sometimes get away with more frequent emails.
Continually refine your schedule to maximize open and click-through rates. There's no one-size-fits-all solution. Monitor performance data and survey subscribers to ensure you've found the optimal balance between valuable content and inbox clutter.
Use Triggers and Life Cycle Emails
In addition to general newsletters and promotions, use triggers linked to user actions and the stage of the product or service lifecycle. Welcome new subscribers, wish them a happy birthday, or send cart abandonment reminders. Tailor your content and cadence based on the subscriber lifecycle stage.
9) Integrating Email with Other Marketing
Email marketing can be even more powerful when it is integrated with other digital marketing campaigns and channels. Here are some key ways to connect email with the rest of your growth marketing efforts
Coordinate with Your Social Media Campaigns
Your email and social media strategies should work together to amplify your messaging. Share your emails on social media to reach new audiences. You can also repurpose email content into social posts. Use social media to promote email signups and vice versa.
Drive Traffic to Landing Pages
Place links to targeted landing pages in your emails to convert readers into leads and customers. Encourage email recipients to visit key pages on your website through personalized CTAs. Conversion rate optimization is key here to track how well your landing pages generate the desired actions (conversions, sales, signups, etc.) stemming from these emails.
Link to Online Ads and Promotions
Email is a perfect medium to direct people to special offers and deals promoted through online ads and other channels. Create consistent messaging and visuals across emails and ads. Use emails to provide details on promotions featured in ads while adding email sign-up forms to ad landing pages can help encourage prospects to take the requisite actions..
Track Leads and Sales Data
Make sure your email and CRM systems are integrated. As our previous point highlighted, this allows you to track the customer journey from email to lead to sale. Identify which emails drive the most conversions. Personalize future messaging based on lead and customer activity was shown via emails. Moreover, this data can be used to optimize your email and cross-channel marketing.
10) Tracking the Appropriate Email Marketing Metrics
To get the most out of your email marketing efforts, you need to continuously track and analyze campaign performance data. This allows you to identify what's working well and what can be improved.
Some key metrics to track include:
Open rates: This shows what percentage of subscribers opened the email. A high open rate means your subject line and preview text are enticing while a low open rate can potentially raise questions about deliverability as well as the level of interest in the email's subject matter.
Click-through rates: This shows how many recipients clicked on links within the email. This helps gauge engagement and interest.
Conversion rates: Ultimately you want to track how many emails result in desired actions such as purchases, sign-ups, etc. This indicates how effective your call-to-action is.
Unsubscribe rates: If many people are unsubscribing from your list, assess why. Too many emails? Irrelevant content? Then consider experimenting with a different frequency while considering alternative content or content angles..
Spam complaints: High spam complaints lead to lower deliverability. Review email content and sending behavior.
