Email and Newsletter Testing Tools

Powerful testing tools save you time, cut out errors and maximise your deliverability.

dotMailer includes advanced testing tools, so you can proof and test your emails quickly and extensively.

• ‘Inbox Preview’ proofing tool*
  How do your emails look when they're delivered?
  
  You need to know because as many as 19% of email recipients will delete an email unread, if it hasn't rendered properly in their inbox!**
  
  You wouldn't print a brochure without proofing it first. That's why dotMailer includes a time-slashing 'Inbox Preview' proofing tool. 
  
  In just one-click you can see how your email and branding look in over 20 key email clients – before you hit the send button. Read more.
  
  
• Subject line split-testing tool
  High performing subject lines are critical for your open rates. And there is only one way to find out which subject lines will maximise your open rates – testing. So dotMailer includes an ingenious split-testing tool.
  
  Use this invaluable ‘open-rate booster’ to simultaneously test two different subject lines in a campaign. dotMailer will analyse which line is performing the best, and switch the rest of your email sends to that winning subject line.
  
  
• Advanced spam-checker
  Along with the Inbox Preview proofing tool, you'll enjoy an advanced spam checker that provides a detailed breakdown of your results.

Plus - free unlimited testing
With dotMailer you can send unlimited test emails to up to 20 email addresses, and preview personalised content. So you can be sure your emails look right, before you actually send them.
