Studies have proved that one of the best ways for brands to reach out to their customers and engage with them is through email marketing. This holds true for a mature audience as well as a young, tech-savvy audience.

That said, no email campaign can be successful if your emails do not reach the intended recipients. This is where your reputation as a sender becomes important. If you don’t have a good sender reputation, email service providers may divert your emails to the spam inbox. You may even be subject to fines. So, let’s take a look at the factors influencing your sender reputation and how you can improve it.

What Gives You A Poor Sender Reputation?

The key reasons why you may get a low sender reputation score are:

  • Recipients often mark your emails as spam
  • Not enough recipients open your emails
  • High bounce rate or a high number of emails sent to invalid email accounts consistently
  • High un-subscription rates

At the crux of these factors lies a reliance on bad data. Think about it – would a person who signed up to receive emails from you mark them as spam? No – this typically happens when information in your database is outdated. For example, if a subscriber signed on to a newsletter with a work email address and later left that job, any email sent to that address would bounce. The good news is that there’s plenty you can do to improve your sender reputation.

Simple Steps To Improve Sender Reputation

You need to check that the email addresses listed are complete, correct and still in use. If you were to do this manually, it would take a lot of time and may additionally inconvenience your customers. Email verification tools conduct this validation without the need for manual inputs from the customer and are much quicker.  Database cleaning should not be a one-time affair but an ongoing process.

  • Use segmented email lists

Customers often mark emails as spam or unsubscribe from mailing lists when the content of the emails do not interest them. Given that you probably offer more than one service, customers have unique reasons for signing up for your emails. To ensure that your emails contain information that will interest your customers, avoid using a single long list but use shorter, segmented lists. This makes it easier to match relevant content to your customer’s needs and preferences. For example, you may segment a mailing list according to the recipient’s location, age, their past purchases, etc.

  • Personalize the subject line

Personalizing the subject line of your emails can increase open rates by as much as 50%. This is one of the simplest steps that can get your message delivered and help boost your sender reputation. Instead of using a generic subject line, use it as an extension of your salutation and make sure you mention the recipient’s name in the subject line.

In Conclusion

Emails are a powerful means of marketing your products and services. By protecting your sender reputation, you can maximize the results from an email marketing campaign.
