Increase your Email Opening rate

Increase your Email Opening rate

Email marketing Guide

One of the most important things when running an email marketing campaign is to have a good Opening rate for the emails that have been sent, and it's easy to land in the spam section even after doing everything by the book. 

However, there are many ways to improve your open rate, so let’s go over them.


Subject line optimization

This is the first thing that your subscribers see when they open their inbox, and it's vital to optimize it as much as possible. Split testing multiple subject lines that cover the niche that you're running from every angle will reveal the winning title. 


Be unique yet effective with the subject line. 

Here are some important tips:

  • Generate curiosity for your email recipients, making people curious enough so they open your email, but there's a fine line of being too mysterious with your subject line, which you should avoid.
  • Numbers attract attention among readers, so including some statistics in your subject line can really improve the opening rate.
  • Being fun and sending a conversational subject line that lightens your recipient's mood can work wonders.
  • There's also the tone and style of your subject line. If possible, research your subscriber lingo, so the text naturally resonates with them.

Another important tip that's often being overlooked is to not get too irrelevant with the subject line so that the recipients don't flag it as spam which would severely affect the sender's reputation.


Avoiding Spam Trigger In Your Subject Line


Spam filters continue to improve in how they vet incoming emails, yet it's still a common thing to land in the spam section, even with a legitimate message. 

One of the most important things you have to do when running an email marketing campaign is to prevent being flagged as spam.

Here are some tips to avoid triggering spam filters and get your message into the inbox section: 
  • Stay away from sales lingo and do not use words like "discount," "cash", or "buy" in your emails.
  • Make sure you're only sending emails to recipients who have opted for your mailing list.
  • Have a reputable IP address that the emails are sent from.
  • Send your emails from a verified domain.
  • Make sure your code for the message is clear and doesn't have any errors.
  • Don't use tactics such as bait-and-switch, which are deceptive.
  • Have a clear opt-out button in your email message.
  • Don't send your email with the subject line having all capital letters.
  • Don't use numerous exclamation marks such as !!!!!.
  • Make sure that the IP reputation is good. It has to be built slowly and messing this step up can completely ruin your domain's ability to send emails in the future. Remember to really take your time in building it. Go slow. Make sure to engage with clickers.
  • One important tip that you can use is shared IPs that have a high reputation already. It's possible to find services that can help you with that.
  • Never include images in your email until you've grown your reputation and it's high.
Increasing the opening rate:
  • Having a preview in your email for what the user can expect. An example of this could be "see who liked you" if it's a dating-related offer.
