By attending to these most critical structures, you can be confident that your messages are not subject to various spam filters and blacklists. They also remove any impediments to DMARC compliance for your domain.
Cons
Con Port 2525 is not encrypted
Most cloud providers block ports 25, 465, and 587. Port 2525 is commonly open but SendGrid only allows unencrypted messages via that port.
Note: There are also so some certificate issues (see https://support.sendgrid.com/hc/en-us/articles/200182008-Certificate-verification-failed-for-smtp-sendgrid-net)
Con Poor deliverability of emails
Con Not suitable for people without a technical background
There are some features which are missing by default from SendGrid (sign-up forms or follow-up messages just to name a few). In order to implement those in your emails, you need to know how to program because you have to code them yourself through SendGrid's API.
Con No sandbox/test mode
Does not support test keys that can be used to check integration with SendGrid and that cannot be used to send real e-mail out. It means that either you don't cannot verify that your integration with SendGrid works during development, or you have to use real credentials which should not be shared widely across your team.
Con Can't view contents of sent emails
They do not capture the sent emails. This means you cannot check that the email was sent correctly, and it makes it harder to debug issues that arise.
