Hey @joey,
This is a good question to ask! I’ve used Sendgrid for a bit of time until recently when I had so many terrible issues with them and their team. Their delivery rates were very low for me, so I reached out to their team and the only solution they proposed for me was to upgrade to their Pro Plan and get my own IP Address which was about give or take $90/mo and just ridiculous.
I actually created a post asking for better service than Sendgrid for Bubble a few weeks ago and @bubble30 pointed me in the direction of Postmark. This thread also pushed me to make the change: Postmark is awesome
I think when considering this question, you might have to look at it using a wider lens and what will be better for you long-term. I’ve been using Postmark for about a few weeks now and mail delivery has been great, they also have a very supportive customer support team who are very responsive compared to Sendgrid.
I’ve used Postmark to send both marking and transactional emails through Bubble.
