Now available: Emoji in subject lines
We had a pretty big couple of months at Postmark. We released some great features to improve the core of our platform, such as Domain Verification and Link Tracking. But today we’re finally righting a wrong that we get a ton of support emails about. Take a breath, emoji-lovers, because emoji are now supported in Postmark subject lines. 👏
In our defense, this isn’t something that we thought would be important for transactional email. Transactional email is serious email, and we didn’t think anyone would want to add emoji to those subjects. But then we started hearing from you about how important emoji has become to help your users recognize your email. Whether it’s a 🔒 to indicate a password reset email, or a 💰 to indicate an invoice, it turns out that emoji can be very useful for transactional email as well.
Two things to note about using emoji in subject lines:
- Some SMTP clients don’t encode all emoji properly, which means they’ll sometimes replace a valid emoji with a �. That’s related to individual SMTP clients, not our implementation of it.
- Be aware that adding a 💩⚖️ of emoji might affect your spam score negatively. So be sure to use our SpamCheck tool before you go crazy. While you’re adjusting your subject lines, also check out Jakob Nielsen’s recommendations in Email Subject Lines: 5 Tips to Attract Readers (this link was included in our monthly Postmark Newsletter, which you should definitely subscribe to).
So here we are. You can now add emoji to your Postmark subject lines, and they’ll render correctly in your favorite email clients. Of course, emoji are already supported in the message body, so there are no changes there.
And with that I’ll just say, go forth and 🎉.
