I'm using Amazon SES and found that there's a limit on verifying identities i.e. 1000 emails (senders) per account.
http://docs.aws.amazon.com/ses/latest/DeveloperGuide/limits.html#limits-sender-recipient
My application is sending around million emails everyday, and I am creating email identites, but now I am coming near to 1000.
What's the best work around to solve this issue? Or is there any chance Amazon will increase it?
Amazon will not increase that for now. You can:
1.- Use 1.000 Verified Senders for each SES region, which totals: 3.000, the more regions Amazon adds to SES, the more Verified Senders you'll have. Today Amazon has SES available on the following regions: Virginia, Oregon, Ireland.
2.- Create another Amazon AWS account, so you have 3.000 more Verified Senders available.
3.- Best approach, not yet available from AWS: create separate AWS accounts for each of your users using AWS API, and then create a user for that AWS account with a Policy which enables that user to use the SES API.
Be careful when allowing so many senders use your SES account. If any of them does malpractice, Amazon AWS team, will right away cancel your AWS account or limit your SES sending capabilities.
First of all, SES is designed to be a "few senders to many recipients" service, not a "many (untrusted) senders to many recipients".
Second, sending emails on behalf of others is not a good practice; instead, use your own verified sender and add the user as a Reply-To: address. In this way, hitting the Reply will send the email to the correct person and you can actually use email signing (DKIM, etc.).
For example:
From: <[email protected]>
Reply-To: <[email protected]>
Subject: ...
Not sure if sendgrid sets a limitation on sender addresses, I couldn't find anything on any limits for that. They may be a good alternative for your use case. https://sendgrid.com/docs/API_Reference/Marketing_Emails_API/sender_address.html
