Email Testing FAQs
If I test my email templates when I build them, why do I still need to test before every individual send?
Email clients and devices change constantly. In fact, one study we conducted found that the top five most popular email clients made a change every 1.2 days on average. Even if your email templates aren’t changing drastically from send to send, any of the changes an email client or device makes can break your email, so testing before every send is the only way to truly send with confidence.
I can see a browser preview of my email through my email service provider (ESP) or marketing automation platform (MAP). Shouldn’t that surface any issues that I need to address?
Every email client and device renders or displays emails differently. While a generic browser preview is great while you build, you should test your email across all email clients and different devices popular with your audience before you send to ensure more nuanced email clients, like Gmail or Outlook, are showing what you expect your subscribers to see.
When should I test my emails?
Testing early and often is a best practice when it comes to streamlining your email workflow and getting the best results. If you test as you build, you can quickly catch and fix errors before your email is routed to stakeholders within or outside of your company for review and final approval, reducing review cycles and getting your email out the door faster.
