Dedicated IP for transactional e-mails sending

Following up our migration from Amazon SES to SendGrid, some users reached out to let us know they wouldn’t receive our e-mails.

Upon investigation, we noticed that their e-mail servers were dropping our e-mails due to the sending server IP address average reputation, as you can see in the following test: https://www.mail-tester.com/test-7vrshajzw

We setup a dedicated IP for sending e-mail in SendGrid, which has dramatically improved our e-mail sending reputation, as we now control that IP address reputation. As you can see on the newer test, deliverability is now perfect: https://www.mail-tester.com/test-vba0dtug5

The users to whom our e-mails were dropped by their servers can now receive our e-mail again.
