So you’ve finally done it. You’ve created the perfect masterpiece of an email signature. You’re happy with yourself (and rightfully so!), so you start sending your emails out.

Sometime later you send an email to a work colleague. You look over their shoulder as they read your email on their smartphone, only to notice that the email signature that you spent so much time and effort creating looks terrible. The text is in the wrong place, images are missing or not animating as they should, and the whole thing just looks a mess. What happened?

The recipients of your emails have the option to read on a whole variety of different devices, browsers, and screen resolutions. It’s surprising how often people forget to test whether or not their email signatures work properly on devices and browsers other than the ones they use themselves.

That’s why today we’ll show you three essential checks you should do on any new email signatures to ensure that they appear picture perfect on every device and browser.

1. Proofread your Email Signature

It’s a well-known fact that it’s much easier for someone else to spot the flaws in your own work than it is for you, so before you do anything else – always get someone else to proofread your signature (or anything else, for that matter!).

It’s such a simple step that will catch obvious problems, but it’s something so many people overlook. Choose your work colleague, a friend or even a family member. The more honest they are, the better. A tool like Grammarly can also help you out

You should tell anyone proofreading your signature to look out for the following:

  • Spelling mistakes
  • Grammatical mistakes
  • Check that any phone numbers, email addresses or other contact details are correct
  • Check that any hyperlinks work and go to where they’re supposed to
  • Check that any dates are correct, especially for any legal disclaimers or promotional offers

It never hurts to have more than one person proofread your work either.

2. Test in different browsers

While your signature may look great in Google Chrome, the same may not be true in another browser like Mozilla Firefox or Microsoft Edge, so it’s always important to check that other browsers don’t do unexpected things with your beautiful signature. Below are the most popular browsers that you should check:

Fortunately, checking this is very straightforward. Just send an email with your signature attached to a webmail address (such as a Gmail or Outlook address) that you own, then open it up in different browsers (install them if you need to).

If you don’t have a webmail address such as Gmail that you can use, there are sites like Mailinator where you can use a throw-away address without even having to sign up.

If you’re using our email signature solution, Crossware Mail Signature, you can click on the Test Email option above any signature and send to your chosen email to see how it will look in the browser you open the email in. Simply do the same again in each browser you want to check.

3. Test on different devices

It’s also important to check how your signature looks on different devices. This, of course, may not always be possible depending on what is available to you, but if you can, you should try to check on as many of these as possible:

  • A desktop or laptop (Windows, Linux or Mac)
  • A smartphone (iPhone or Android)
  • A tablet (iPad or Android)

When testing on these devices, be sure to look out for particular quirks of the platform. For example, when sending an email from a smartphone or tablet, they often append their own signature in the form of “Sent from my iPhone” (or similar), so it’s worth making sure the device you send from has options like this disabled so that it doesn’t mess up your lovely new signature (if you’re looking for a quick tool to do this, Crossware Mail Signature can automatically remove “Sent from my iPhone” or any other phrases for you as you send your email. This will be applied no not matter what device you’re sending from).

Of course in practice, there comes a point of diminishing returns, but the more devices, browsers, applications, etc. that you can test on, the better.
