Sender Reputation and Deliverability Mistakes

Deliverability rates are the most important metric of email marketing, and this is why it’s the first topic we take on. 

Let’s check out the common errors that can lead to dropping deliverability rates and a poor sender reputation.

1. Not Monitoring Deliverability

Without tracking deliverability, email marketers won’t know if their emails reach inboxes or land in spam folders. If emails aren’t reaching subscribers, all the time and money invested in crafting the campaign is wasted.

Early detection allows you to take corrective action and correct course so your future emails reach the primary inbox.

A strong sender reputation can cure your deliverability woes, but that’s another common mistake email marketers make.

2. Not Caring for Your Sender Reputation

If you’re wondering why sender reputation matters, this table breaks it down:

Why sender reputation matters	Its effects
Superior inbox placement	A good sender reputation increases the chances of emails landing in the inbox, not spam.
Improved campaign performance	Higher inbox placement leads to better open rates, click-through rates, and overall campaign success.
Good brand reputation	A positive sender reputation reflects well on your brand and builds trust with subscribers.
Long-term deliverability	Maintaining a good sender reputation ensures consistent email deliverability over time.

  

One of the first things you should do for your sender reputation is add security protocols to your email domain — another task email senders commonly overlook.

3. Not Getting Authenticated

Authentication protocols work together to ensure your emails are delivered safely and securely. They act as a digital ID, verifying you as a legitimate sender and boosting the chances of your emails landing in the inbox.

Without authentication, emails from your domain are more vulnerable to spoofing. Authentication protocols make it clear you’re the real sender, protecting your brand image. The biggest reason to get authenticated is that email providers like Gmail and Yahoo now require all bulk email senders to have these protocols in place.

4. Not Maintaining Email Lists 

Blasting emails to outdated or unengaged addresses is a waste of time and money. You’re spending resources crafting email campaigns a significant portion of your list might never see. 

Inactive subscribers are unlikely to open your emails, click on links, or convert into sales. This leads to poor campaign performance and a negative impact on your sender reputation.

The solution? Regularly cleaning your email list.

3 Major Lead Generation and Contact Management Blunders

If you’re seeing poor email performance, the problem may not be your campaigns at all — it could be the way you collected leads or how you manage contacts on your email list.

These seemingly harmless issues can wreck your email marketing results. Read on to learn what they are and how to avoid them.

1. Buying Email Lists

Buying email lists is a tempting shortcut for email marketing, but it’s a shortcut paved with pitfalls.

People on purchased lists haven’t opted in to receive your emails. They’re unlikely to be interested in your content, leading to low open rates, clicks, and conversions. 

Sending unsolicited emails can be marked as spam, potentially landing you on blacklists. This can make it difficult to get future emails delivered even to legitimate subscribers.

2. Emailing Leads without Permission

3. Not Segmenting Lists

Email list segmentation is vital in email marketing because it allows you to send targeted messages that resonate with specific subscriber groups. Segmentation lets you focus your marketing efforts on those most likely to convert.

By segmenting your list, you’re making each email more effective. When subscribers receive messages relevant to their needs, they’re more likely to click on links and take action. With segmentation, you also reduce the likelihood of spam complaints and unsubscribes.

7 Common Errors Related to Email Content and Design

Email marketers tend to make mistakes during the email content creation and email design processes. We compiled the most common ones so you can avoid repeating them.

1. Sending Irrelevant Email Content

Irrelevant emails frustrate subscribers. If they consistently receive content that doesn’t resonate, they’re more likely to unsubscribe from your list entirely. This shrinks your audience and weakens your marketing reach. 

Bombarding subscribers with irrelevant content portrays your brand as careless or out of touch. This can damage your brand image and erode customer trust.

2. Excessive Sales Talk

People who give you their email addresses aren’t signing up for a barrage of sales pitches. Email subscribers are looking for valuable information, not constant sales pressure. 

Focus on providing educational content, industry insights, or helpful tips. You must build trust with your audience. Subtle sales techniques like product recommendations or highlighting limited-time offers can be effective without being overbearing. Focus on the benefits your product provides and let the value speak for itself.

3. Boring Subject Lines

Imagine a crowded inbox overflowing with emails. Bland subject lines like “Company Update” or “This Week’s Newsletter” would be immediately skimmed over. As the subject line is your first impression, boring lines scream “unimportant” and lead to low open rates.

A well-crafted subject line can be the difference between a delete and a loyal customer. It sets the tone for the email and piques subscriber interest, hopefully leading to higher engagement and click-through rates.

4. Poor Copywriting

Even if emails get opened, poorly written content fails to capture attention. Typos, grammatical errors, or dull writing styles lead to quick deletion and wasted effort. 

Poor copy hinders your ability to build relationships and nurture leads. Engaging and informative content is key to establishing yourself as a trusted resource and driving long-term customer value.

And remember— avoid email cliches, proofread your email, and test your links before you hit that send button!

5. Not Using Email Personalization

If you send generic marketing messages, you might as well not send emails at all.

This is where email personalization can give you an edge. Using a subscriber’s name in the subject line or greeting makes your email stand out and feel more relevant. People are simply wired to open and interact with emails that speak directly to them.

Additionally, when subscribers receive targeted offers or recommendations tailored to their needs, they’re more likely to convert.

6. Writing a Dull, Tepid CTA

The CTA is probably the most critical part of your email. It’s the clear and compelling nudge that tells subscribers what you want them to do after they read your email. 

Without a clear CTA, subscribers feel unsure of the next step. Imagine writing an excellent pitch and then leaving zero directions on what to do next. An excellent CTA is specific and action-oriented, using strong verbs like “Download Now” or “Shop Today” — but there are more creative options, too.

7. No Mobile Formatting or Using Poor Templates

Overused or poorly designed templates scream “unprofessional” and make your brand look cheap. This reflects badly on your brand image and reduces subscriber trust. 

The same goes for emails that aren’t mobile-responsive; on smartphones, they appear jumbled, with text too small to read and buttons difficult to click. 

The solution for these issues is simple; use modern, responsive email templates that automatically adjust to the device being used. This ensures your email looks great on desktops, tablets, and smartphones.

5 Frequent Sending Practice Fails

Sending practices are closely monitored by email providers and ESPs, so you can’t afford to mess up here. Here are the top 5 missteps to avoid.

1. Warm Up Your IP and Domain First

Sending a massive email campaign to your list before you properly warm up your IP and domain can lead to your messages making a beeline for the spam folder. Sudden bursts of emails from a new source can also trigger spam filters.

Email providers rely on sender reputation to determine where to deliver emails. A new domain and IP have no reputation yet. Warming up gradually shows email providers you’re a legitimate sender. 

The best way to do this is by sending emails to a small group of trusted contacts, like colleagues or friends who have opted in. Slowly ramp up the number of recipients over time, starting with a segment of engaged users. Monitor bounce rates and spam complaints during the warmup process.

2. Forgetting To Send a Welcome Email

Not sending a welcome email to a new signup is a missed opportunity because these emails generate 4x more opens than regular emails. 

It’s your first chance to make a positive impression on new subscribers. It sets the tone for your relationship and establishes expectations for future messages. Welcome emails are a great platform to introduce your brand personality and voice.

You can even use them to collect additional information about subscribers through preference centers or surveys.

3. Inconsistent Email Volume and Poor Send Timing

Bombarding subscribers with excessive emails is the most surefire way of killing your email marketing operation. Not only does it set off spam filters, but your engagement will also suffer as readers lose interest due to email fatigue. And if you send too few emails? Subscribers will be left wondering why they signed up in the first place. 

Consistent and cleverly-paced emails keep your brand at the forefront of subscribers’ minds. They’ll be more likely to remember you when they’re ready to make a purchase.

On a similar note, send emails when subscribers are most likely to check their inboxes. This strategy also applies to cart abandonment emails; reminders are most effective soon after the specific action (abandoned cart) occurs.

4. Not Using Automation Effectively

Not all email marketers use email automation to its full potential. Automation can be a blessing when you set it up correctly, as it efficiently takes over all your manual work.

Automated emails based on subscriber behavior lead to higher campaign engagement. Targeted content and personalized offers delivered through automation nurture leads and drive higher conversion rates.

Most importantly, automation allows you to manage a growing subscriber base efficiently without sacrificing personalization or timely communication.

5. Not Following Email Regulations

Numerous regulations around the world, like the CAN-SPAM Act (US) or GDPR (Europe), govern email marketing practices. But why should you care? 

A convincing first reason is that non-compliance can lead to hefty fines or jail time. Secondly, compliance violations can hurt your sender reputation, making it difficult to deliver future emails.

Paying close attention to these aspects can help you comply with regulations:

Regulatory authorities insist on:	What the rules mean for email marketers
Permission-based emails	Always obtain explicit consent from subscribers before adding them to your email list.
Transparent communication	Be upfront about who you are, what type of content you send, and how often.
Unsubscribe options	Always include an easy-to-find unsubscribe option in every email. Adding a physical address is also required.
Data security	Take steps to safeguard subscriber data and prevent unauthorized access.

3 Principal Tracking and Reporting Errors

Now that your campaigns are well on their way to your subscribers, you can kick back and relax, right? 

Nope!

Below, we review mistakes made by email professionals during the tracking and reporting phase.

1. Poor Data Collection Practices

Many marketers undermine the importance of accurate data collection, leading to campaigns that fall flat. If you aren’t closely monitoring your campaign metrics and decoding what they mean, you will end up repeating the same errors until you lose all your subscribers. 

You must analyze the results of each campaign and keep a close eye on stats to see how receptive your audience is. You must also study your delivery stats and use features like email tagging and segmentation to organize contacts.

2. Ignoring Data Trends

An extension of monitoring your analytics, you must be attentive to catch trends or major changes in your audience. 

By analyzing trends in post-campaign data, you can identify shifts in subscriber preferences. Maybe interest in a certain type of content is declining; perhaps a recently introduced subject line format is generating more engagement. Analyzing trends helps you adapt your strategy to what resonates best with your audience currently.

Studying campaign reports can also reveal what industry-specific trends work best. For example, certain types of emails or email elements (like infographics or video content) could drive higher engagement.

3. Not A/B Testing

Without split testing, you might be leaving valuable engagement and conversion opportunities on the table. Your emails could be performing sub-par simply because you haven’t identified the best approach for your audience; you simply cannot rely on intuition or guesswork.

A/B testing helps you refine your approach and ensure your emails are working as hard as they can. 

Split testing can reveal surprising insights!
