I am building a web app that will send SEO reports via email and I am on the lookout for a decent provider to deliver emails.<p>I understand that Amazon SES is the cheapest when it comes to sending emails. I am not sure how good their email deliverability is.<p>Other options are Postmark (somewhat pricey), Mailgun and Sendgrid. I would like to know which email providers are preferred by the HN community.
We've had quite a lot of experience using Amazon SES, as we run an email marketing platform on it. We run both our marketing and transactional emails using it for <a href="https://emailoctopus.com" rel="nofollow">https://emailoctopus.com</a>.<p>If you're already using AWS then I'd definitely look at SES. I appreciate the price may seem too cheap, but the service is now used by huge companies for their transactional emails, the likes of Netflix rely heavily on it. As long as you configure your set-up correctly with DKIM/SPF I'd be surprised if you ran into too many delivery problems. Also worth noting they now offer dedicated IPs, for a not too costly monthly fee.
Mandrill, Mailgun, Sendgrid, SES... they've all got their place.<p>I find the deliverability comparable (although I'm least experienced with SES). Where they shine perhaps, is in reporting and tracing of issues.<p>Postmark do look good and perhaps with _only_ transactional email, their deliverability could be among the best.
I tried a few ones and decided to go with Mailgun.<p>All the providers mentioned are targets for spammers. So they have to somehow whitelist your account before they allow you to send at full speed.<p>In that regard I found Mailjet to have the worst on-boarding experience, and Mailgun to have the best.
Never had a problem with SES deliverability personally. You do get the odd end-user email address on the suppression list but that's not often. I've only used their SMTP set up though, no SDKs or anything like that
I have gone from Mandrill to Sendgrid and back to Mandrill. Personally, we had tons of issues with Sendgrid (too many blacklisted IPs, emails being delivered late etc) but Mandrill has been rock solid.
