Ask HN: Best provider for sending transactional emails?

20 pointsollieco8y ago26 comments

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.

I understand that Amazon SES is the cheapest when it comes to sending emails. I am not sure how good their email deliverability is.

Other options are Postmark (somewhat pricey), Mailgun and Sendgrid. I would like to know which email providers are preferred by the HN community.

Postmark has been excellent for me. Transactional only. I believe you get 25,000 emails for free, and then very reasonable after that.

I can't which one is the best. But we use MailGun and we are not happy with it. We will probably switch to Postmark.

I use both on free tier and I am happier with PostMark.

I had several issues when sending to Microsoft (hotmail, msn, etc.) domains via MailGun because someone exceeded granted quota for outbound IP address and since then I balance outgoing emails using both.

As mentioned by others, MailGun support doesn't care much about queries from free tier users so I would go for PostMark if I had to pay (more intensive use) or recommend to someone.

I also never faced an issue with MailGun, though I mostly use smtp not their http api.

Is there any specific issue you ran into?

For us it takes too long for the messages to be received with mailgun.

Why aren’t you happy with MailGun? I’m a customer and I haven’t had any issues with it.

MailGun's support is horrible. I kept emailing them to let them know about login issues, and it would take them a week to get back to me. After a couple tries, they just dropped the ball and stopped following up on the ticket. Message received.

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 https://emailoctopus.com.

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.

My company (and my last one also) uses SES. It's got both a REST API and SMTP endpoint, so for most apps all you need to do is reconfigure the settings.

If you already have EC2 instances, the free tier of 62,000 messages should be comfortable for a lot of teams.

I'm a fan of SendGrid. Never had a problem.

davewasthere8y ago

Mandrill, Mailgun, Sendgrid, SES... they've all got their place.

I find the deliverability comparable (although I'm least experienced with SES). Where they shine perhaps, is in reporting and tracing of issues.

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.

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.

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.

Provided you can code all the necessary unsub/bounce/report modules and display logs yourself, AWS SES is the cheapest and it works well.

tmaly8y ago

I have used mailgun without any issues. The free tier is nice and I was not forced to have a paid plan when I got started.

gt565k8y ago

Mandrill has the best features, but depending on your volume, their pricing might not be the best.

tixocloud8y ago

I've been pretty happy with Mailgun thus far. Their free tier is what got me started.

jst908y ago

What volume are you looking at?

originof8y ago

Sendgrid is really good

zerni8y ago

Definitely sendgrid!

pvsukale38y ago

Try Spark post. Their free plan is good.

bharani_m8y ago

Stay away from Sparkpost. They will put your account on hold without any warning (and for no good reason) and then their support team takes ~2 days to reply.

RaspyRoe8y ago

We use mailgun but there are a bunch of wierdly dropped emails. Am I to hope that would change with something like Postmark if not with Sparkpost? The fact is that we always use the lowest tier of paid plan since our volume is not too big and dont feel that we are an "important" user on a lot of services.
