Overall Satisfaction with Twilio SendGrid
[I'm] Using SendGrid to send transactional email, as well as updates and newsletters, for several websites that I control. Not using any of the advanced features of SendGrid, really, beyond their whitelisting, DNS-based security, and such. For the most part, it just works, and I don't have to think about it, which is wonderful. (I spent many years wrestling with mailman and the like; when I first switched to a dedicated SMTP server it was a revelation!)
- Deliverability seems good. Never had any issues here.
- Whitelabeling works well, making it appear that emails are being sent directly from the domain (no evidence of SendGrid anywhere except maybe if you dig into the email source).
- Admin interface is clean and easy to use.
- Prices used to be a little more flexible, starting at $1 and going up according to usage – and that included whitelisting and all that good stuff. Now they start at $10 a month although that does give you up to 40,000 emails a month. They also have a free plan (< 100 emails / day) but I'm not sure if it includes whitelisting.
- Had some issues with the SendGrid API years ago. They probably fixed it, but I've since just used the SMTP endpoint with no issues.
- ROI? Email is crucial for many online businesses and websites, including mine, and SendGrid handles my email needs without much fuss. So definitely a positive impact.
I've looked at or tried other services but they're either more expensive or have more "reliability issues" stores attached to them. Honestly, SendGrid was the first service I ever used for outsourcing email delivery, so it's comfortable and familiar, and it's "just worked" for basically a decade so it would take a lot for me to switch.
