The install guide offers a handful of email providers for Discourse. I was wondering if people could chime in with their feedback for the ones mentioned in the guide (Mailgun, Elastic, SendGrid, Mailjet).
I used SendGrid on an install and it took awhile to get it to work correctly. I had to verify with five separate CNAMEs to verify the site and get emails not to end up in spam folders.
What has been the most painless service for you? And is the verification process the same for every provider?
@pfaffman may have thoughts
I just did a new setup with Mailgun and it was substantially easier than SendGrid was.
I’ve found mailgun to be very simple and effective. Their dashboard tells you exactly what you need to configure and checks DNS regularly to make sure records stay intact. The rest of their platform is rather simplistic, if you’re looking for more in the way of analytics you may be better paying the premium and sticking with Sendgrid.
Last time I checked MailJet and SendGrid were equally priced, but MailJet didn’t really offer much over cheaper options such as MailGun and ElasticEmail.
I’ve only worked with Elastic Email a couple of times. They do talk about mail reputation on their platform being affected by email volumes below 10,000 messages, so they might be a bad starting point for small communities.
As to ‘best’, it very much depends on your appetite for this kind of stuff. Setting up CNAMEs is par for the course with everyone. All of the companies you’ve mentioned are experts in mail deliverability and that’s part of why they’re recommended rather than running a local SMTP server. If you give us more information on your community size and estimated volumes it would certainly help.
My community is very small. A better topic title should be “Easiest Email Providers”. Mailgun had fewer records to work with and got up and running faster, which is what I was looking for. Serious analytics is out of my range so Mailgun was just what I needed.
I’m mainly looking for feedback from other uses as to if they encountered any roadblocks or had their feedback about a particular service.
Mailgun is extremely good, I’ve set it up months ago and I’ve never even went back on to check anything because there are never any errors or limit problems.
Give it a try, 10,000 emails a month for free.
I use Amazon SES. Give it a try 
SendGrid を使用していましたが、Discourse フォーラムを設定した後、Discourse が大量のメールを送信するため、スパマーだと判断されて SendGrid アカウントが停止されました。サポートに連絡しようとしましたが、返信がなく、2 日経ってもフォーラムでメールを送信する必要があり、いずれにしてもより良いプロバイダーが必要でした。無料で本当に良いものはどれですか？
「無料」と「本当に良い」という言葉は、めったに両立しません。
信頼性の高いトランザクションメールは、多くの場合、価格相応です 
はい、無料でおすすめの Discourse プロバイダーはありますか？
私はAmazon SESのユーザーです。無料枠があり、非常に安価ですが、設定は決して使いやすいとは言えません。
例えば先月は、12,040通のメール（3,000通は無料、それ以降は1,000通あたり0.10ドル）で0.90ドル請求されました。
クール！もっと使いやすいものはありますか？
