removing 'via sendgrid.me' from mail sent using on heroku

Question

I'm using the free sendgrid plan to send email from my rails app hosted on heroku. I set it up using a combination of these instructions and this tutorial

It's all working, but on gmail the it the sender comes through as '[email protected] via sendgrid.me'

Is there any way to get rid of this?

I've had a look at this forum but it's not very clear on whether it's possible.

If I can't remove it, can anyone recommend an alternative, free, service?

Answer 1

Yes it is possible, I just did it!

Login to your sendgrid dashboard. Then go to My apps -> DKIM -> Settings then select "Set the DKIM domain to match the FROM domain" By default, Domain is set to "sendgrid.me".

DKIM documentation

The problem is once you do that, all the emails will likely go in the spam folder... So because of that I switch back to the default settings.
