How to set myapp.herokuapp.com mx record to point to mx.sendgrid.net?

Question

I am trying to get my mail exchanger record to point to sendgrid, but I cannot seem to find the option on heroku. Does anyone know where this setting is located?

Answer 1

Unfortunately, as far as I can tell, Heroku does not allow you to set MX records for their subdomains.

To counteract this, you can do one of two things. You may setup MX records for some domain (or subdomain) you own, and point that to SendGrid. OR you may use the preconfigured bymail.in. This service has MX records preconfigured to send to SendGrid. To use it simply direct your users to email your-sendgrid-or-heroku-username.bymail.in (e.g. yay@nquinlan.bymail.in).
