| Test thoroughly to improve performance | If you want to maintain a high open rate and stay out of junk filters, you should perform tests to make sure your campaigns are problem-free. | | Test Emails and A/B Campaigns | | View your campaign in a popup preview once the design is complete for a quick visual once-over, and to check the dynamic content if you included merge tags. And don’t forget to send test emails, so you can examine a campaign in different email programs before it goes out. A/B testing allows you to try out two different subject lines and send times on a test group within your list. The best response determines the winner, and we’ll automatically send the winning campaign to the rest of your list. | | | Delivery Doctor | | If you're getting flagged as spam and can't figure out why, get some intel from our Delivery Doctor. It'll analyze your campaign and point out the weak spots, then give you specific pointers on how to strengthen them. | | | | | | | |
