Testing your emails is an essential part of any email marketing campaign. You want to make sure that the email looks right, has no errors, and gets the highest deliverability. As email testing is the best way to refine your email campaign strategy, you must test your emails. In this blog, we will check out in-depth about the best email testing tools available.
What is email testing?
Email testing enables pre-send and robust testing of your emails like inbox rendering previews, in-app spam testing, email validation and more. It enables you to show a preview of how email can perform across different spam filters, devices, and inbox providers before sending.
Why should you test emails?
Performing email testing helps you spot common errors like how your subject line appears on different devices, if the font and HTML look fine, etc. The email that looked good in your inbox might not look the same to other recipients, and this is why you should test your emails over different email clients. A single mistake can make your business fail.
How is email testing done?
Before diving in-depth into the procedure, let's understand the basics of how email testing is done.
1. Content testing (Subject line, proofreading, etc.)
It deals with identifying the grammatical errors and sentence construction errors in your email copy.
2. HTML validation (Preview, fonts, links, etc)
Checking every link in the email copy ensures that any hyperlinks you have provided to the web pages in the email are opening on every browser as intended.
3. Deliverability testing (for spam filters & domain reputation)
It can be done in two crucial steps, namely manual and automated email testing. But manual testing is complicated when your number of emails is high. The superior option that can be used to test emails at present is an automated testing service. In this case, you need not maintain any labs, and you can provide screenshots of different email displays. Testing services contain a spam risk assessment for finding email deliverability problems and correcting them. Various automated email testing tools can make your work easier.
