Include a Subject Line in a CTA Button

[SMartinSJC]

I've got a Landing Page that has two CTA buttons and, while they both send an email to a specified address, they're for different purposes (one to request a report, the other to request a call). Because of that, I'd like the subject line to auto-populate with the relevant subject (report or call). I know that can be done in HTML with code in the mailto: link, but is that possible with a CTA button?

Hi @SMartinSJC,

This works in some HubSpot tools but not consistently in others. I'd always recommend testing this from different devices (for example, custom mail to links in marketing emails don't work on certain devices ).

From a first glance in the CTA tool, it seems to work fine:

Testing the CTA, it opens my email client and populates the fields correctly.

This is the generator I used: https://mailtolinkgenerator.com/

Hope this helps!
