11 Email Marketing Mistakes to Avoid

We often click on emails saying, “Hurry Up, Offer Ends Soon!” – only to be greeted with a generic message, broken links, and no clear call to action. Some emails even give us the vibe of the 2000s due to their awkward formatting and so many pictures that load information slowly.
These major email marketing mistakes could negatively affect your brand’s reputation. Globally, 376.5 emails are sent and received daily, while only 21% are opened, with a 3% conversion rate. So, to stay ahead of the competition, your emails must stand out for many good reasons.
Knowing the common email marketing mistakes and how to avoid them can significantly boost your efficiency and build a solid foundation. So, in this article, we’ll discuss the common email marketing mistakes to avoid with a helpful guide. Let’s dive into it.
How Email Marketing Mistakes Drain Your Efforts
Mistakes in email marketing can have serious consequences. Ineffective marketing strategies can cost businesses a lot of money. They make potential clients distrustful. An email full of mistakes could be reported as spam. It can also decrease deliverability and harm your reputation.
Also, mistakes like sending emails with too many photos or irrelevant material make people unsubscribe. Thus, it will eventually reduce the quality of your email list. So, if you don’t personalize your content or optimize for mobile, you risk consumer interactions.
So, the cost of email marketing extends beyond the immediate losses. It can an impact on the ROI and long-term trust of your company.

1. Emailing Inactive or Unverified Contacts
High bounce rates, poor deliverability, and possible spam blacklisting are the results of an oversized email list that contains invalid or inactive contacts. Your future reach may suffer if your email service provider (ESP) flags your campaigns as low-quality due to frequent bounces or opened emails.
You can improve email deliverability and engagement rates by sending emails to a clean and active email list rather than sending out emails blindly.
How to Fix:

- Use weMail’s segmentation feature to find inactive subscribers, then send them tailored re-engagement emails.

2. Not Customizing Emails
Generic emails that lack personalization result in low open rates, high unsubscribe rates, and disengaged audiences. They come out as robotic and impersonal. Today’s consumers expect brands to understand their interests, preferences, and habits.
Customized emails can boost engagement and trust while increasing conversion rates by making the audience feel valued. Explore the best email customization tips.
How to Fix:
- Use weMail smart tags like {first_name}, {last_name}, and {custom fields} to customize emails for each recipient.

7. Failing to Authenticate Your Emails
Unauthenticated emails might never make it to the recipient’s mailbox. ESPs may flag your emails as spam if SPF, DKIM, and DMARC are not set up, which would decrease deliverability. Emails that are properly authenticated are trusted and go to the recipient’s mailbox.
