Mistakes with email lists in the focus point

As we pointed out already, emails are one of the cost-friendly options of marketing, which also has the highest ROI. So, while doing the email marketing, you have to make sure you don't make many mistakes there. To ensure that, pointing out the common email listing mistakes need to be laid out clearly. Here are those;

Neglecting email verification

Like any data, emails get outdated over time. The decay rate for email is nearly 28% per year. It means if you have a list of 100 emails in your database, 28 of them are no longer active. Also, if you set a budget for sending emails per dollar each then you have to lose $28 for sure. Because you might have used the old database.

One thing that could have saved you here is email verification.

Maintaining a verified list of emails in your email marketing database is the standard choice here. Relying on an email verification company is the better option. Otherwise, you can go for email verification tools that promise quality verification support.

Verifying emails will reflect mismatches in your email data. Mostly it will highlight;

  • Typos
  • Incorrect names
  • Wrong syntax
  • Invalid address format

Once the verification is completed, you'll get error-free lists of emails. It can easily bring efficiency to your email campaigns and help you reach your audience with the right message.

Don't doubt your email strategy

Just verify your email lists once. Trust on expert email data verifiers.

Postponing email list segmentation

Everybody doesn't prefer the same things, even if it's just an email from your company. You need to focus on the pain of each segment of your email recipients. They can catch your message better when you talk about their pain points.

When you segment your audience for email campaigns, it will generate more responses. Plus, you can develop a personalized email strategy based on your segmented customers' preferences. Companies prefer segmenting their email lists for better open rates, reducing unsubscribe rates, and providing better deliverability.

If you want success from your email campaigns, you should never postpone segmenting your email lists.

Sending emails w/o permission

Taking consent while collecting emails is a must. Sending emails without the receiver's permission makes the entire purpose a flop. Sending emails without permission is a direct spam activity that can restrict your email outreach capacity.

Most of the email service providers have spam-combating mechanisms nowadays. It does not allow receiving anything irrelevant.

Many people will "unsubscribe" from your emails, and that's quite natural. You have to make a separate email list for them. Once a subscriber opts out of your list, you should not target them again. Basically, this subscribers' email list will keep your email consent in check.

Undermining subscribers' feedback

While unsubscribing to your emails, your email recipients may have shared some feedback. You shouldn't ignore it at all. To become a champion of email marketing in your field, you should always value your unsubscribers' feedback.

Please consider feedback loops.

Placing the privacy policy guide in front is the need of the hour in this situation. Be very sure that you're not breaching any privacy matters while sending emails. Keeping your email list hygiene and following up on all white-label practices of email marketing is super important here.

Clean email lists are non-negotiable, but you also need to manage unsubscribers' list. Understand why some prospects have opted out of your emails. You have to try out new strategies to re-engage with this audience. At this time, applying the feedback they shared before leaving may help you frame strategies.

Reduce email list mistakes

Taking care of your email listing database to the utmost level is one thing, and keeping it clean and updated is another. Both things will ensure the success of your email marketing campaign. Unfortunately, most marketing companies focus solely on building the email list and often neglect its regular maintenance. As a result, ROI from email campaigns can be reduced even if you try harder.

Regular email cleanup and appending the email database with additional valuable information are equally important. Companies that are performing better email campaigns, like HubSpot, Airbnb, Grammarly, etc, consider email verification and regular email list clean-up.

Now it's your time to maximize your email listing potential.
