I should've checked the reviews before trying. Everybody thinks this company is one-star!Everybody is right. We wanted to use a relay service to allow internal software (cloud alerts and our continuous delivery product) to be able to email our engineers and managers. sendgrid's website let us sign up for the service and start emailing, but the emails never showed up. there was no error or anything. i figured we had done something wrong in the setup so contacted support. they wrote back saying we need to be approved and describe our use case.this is sort of typical because if you are a spammer, you will hurt the relay's ability to send mail. however for our use case, we are emailing about 4-5 email groups which are all under our company domain. there's no marketing.support could not understand this. they were trying to have us fill out a form that had stuff like how we build our email lists and where our opt out form is. again for email marketing, makes sense but not for emailing a handful of internal emails that you yourself own. should be simple.the person could not understand this. i suggested maybe talking to someone more experienced, and she refused, said she would close ticket and only open it if i would speak with her.if she wouldn't have said this, i wouldn't have written a review. her rudeness led me to see that 77% of people (as of 3/1/2023) have given sendgrid a 1-star review. lesson learned, check reviews first! (also don't bother with sendgrid, there are services that have figured this stuff out and you can get working in a few minutes w/little hassel).
