<\/span>Email Deliverability, What to do when emails are going to Spam?<\/span><\/h2>\n\n\n\n
If after testing your email deliverability<\/a>, you find a low score, it\u2019s easy to get confused as to what went wrong. Here are some common issues marketers struggle to get their emails to readers\u2019 inboxes: <\/p>\n\n\n\n
- \n
- A high number of spam complaints<\/strong> – the obvious one, this type of deliverability issue occurs when too many readers report your email as spam. <\/li>\n\n\n\n
- Technical problems with content or configuration<\/strong>. When your email HTML is invalid or authentication is wrong or not set at all.<\/li>\n\n\n\n
- High bounce rates.<\/strong> Emails don\u2019t reach email inbox because too many emails bounce, which can be caused by sending to old email addresses that haven’t been mailed in a while or lots of fake \/ unconfirmed email addresses. A bounce means the email inbox is either temporarily unavailable or the address is not available at all.<\/li>\n\n\n\n
- Low engagement.<\/strong> Despite getting your emails, readers aren\u2019t interested enough to open, engage, or click on links in them. Some ESPs track the audience\u2019s behavior and will eventually stop delivering the brand\u2019s messages if they are not interacted with. <\/li>\n\n\n\n
- Changing to a new ESP or failure to warm up IPs<\/strong> and domains. This type of behavior is considered suspicious by ESPs since it\u2019s typical for spammers, eager to hide their traces. This is why it is always good to talk with your new ESP about deliverability<\/a>.<\/li>\n<\/ul>\n\n\n\n
<\/span>4 easy steps to test email deliverability issues and deal with them<\/span><\/h3>\n\n\n\n
There is no universally accepted rule to fix the deliverability difficulties at once. However, you should be aware of these four pieces of advice and try to implement them in practice.<\/p>\n\n\n\n
Clean your email lists.<\/strong> To avoid sending to low engaged or bad email addresses, clean your list thoroughly to protect the campaign from bouncing and avoid deliverability damage. You can use any email validation tools before send and \/ or engagement statistics from your ESP to find subscribers with low engagement.
Warm up before the game.<\/strong> Warm up the IP and email address before starting a campaign, act gradually. At the initial stage, start sending letters in small batches to subscribers that are known to engage with your emails and slowly increase sending volumes as you get some credit from the receiving inbox providers like Gmail, Hotmail, Yahoo, etc. <\/p>\n\n\n\nRespect subscribers.<\/strong> Get subscribers\u2019 consent before sending emails. You have to avoid buying lists or adding addresses to the base without a recipient\u2019s permission. It’s rather unethical and inefficient and can lead to a lot of spam complaints. If you are not sure the correct permissions are in place, it might be a consideration to do a well-planned re-permission campaign. <\/p>\n\n\n\n
Correct your HTML and add email Responsiveness.<\/strong> We use different devices, so sites and emails with responsive tables, text. Spend time to make sure your emails are responsive or use a responsive email template builder. And don’t forget about testing mobile emails either. Test email content to make sure it\u2019s mobile-friendly, scalable, and readable. This way, you will increase the campaign\u2019s engagement rates. <\/p>\n\n\n\n
<\/span>What is the best email testing tool?<\/span><\/h2>\n\n\n\n
So by now, you understand that email testing is a crucial part of a campaign’s success. It informs of how well emails will do to get to the reader\u2019s inbox. There is hardly any way to do email Quality Assurance without automated email campaign testing tools. <\/p>\n\n\n\n
