Add alt text to CTA's for SEO
Jennifer London commented
I'd second this, but for a slightly different reason. iPhone and iPad users who have turned off the factory setting for downloading remote images only see a blank outlined box where the CTA is in an e-mail. There's no indication of what it is or that it's something they can click on, a real problem for the very element we're using to get them to take action. Adding the ability to add alt text to a CTA would give us the chance to include, at a minimum, the same text that's displaying in the CTA image, and improve our click-throughs.

I also noticed this as a Page Performance error, "Page has images without alt text." for any pages I created that include a HubSpot call-to-action button. It would be nice for the CTA to include in alt="" and title="" tags automatically.
