Gmail versus own mail server for large websites

Question

The web application should send many letters: notifications, news, confirmations, etc.

On a small website, I use Gmail to send my email messages to users.

But which email system uses large sites? (for vs against)

thanks

Answer 1

You can use your own server simply by using the API of your languages ​​for sendmail , or you can use one of the various hosted mail services designed for web applications ( SendGrid , Postmark , etc.).

As for the disadvantages of using gmail, all your emails will be "sent through gmail.com" in their headers, which does not give much confidence that this is actually from your site. If you set up your own mail server, you can use SPF and DKIM to prove that the message is valid from your site. Most hosted services also (I believe) admit this. Thus, your email address is less likely to be marked as spam or may not be trusted by the user or the mail server.

As others have noted, gmail can also appreciate the restriction on sending emails, which is a huge drawback when your emails do not reach your users quickly or may not work at all.

Answer 2

Gmail will block you if you send too many emails from Gmail to the user (you will be detected by spam)

It's best to host your own mail server because it looks professional when you send an email to your users. Few things to take care of when hosting your own mail servers.

 1. You have get whitelisted on Yahoo mail service. 2. Setup domain keys and spf records properly and get them tested. 3. May need to deal with several spam checkers and get into their good books by not spamming. 4. Setup reverse DNS for all the machines from which you are sending mails. 5. Also check that your IPs are not in any blacklist. 

You can use the blacklist http://rbls.org/

or you can use hosted services like Amazon Aws - Simple Email Service

Answer 3

I expect that most large sites have their own mail servers.

Using gmail is a pretty bad idea, I expect them to close their account if you send an inhuman amount of mail.

Amazons A simple email service sounds interesting, but I don't take much time to learn it.

Answer 4

Large sites spend time and money creating mail systems (mail servers, SPF records, making sure that they are not in spam lists or black lists, testing), or they pay for sending their mail through a third-party provider.

Sending bulk email reliably is very difficult. I recommend paying for a relay service, such as AuthSMTP , if you do not have the experience or time.
