Bulk Email Verification Solution and Send Email with SES

Thank you for your questions about implementing a large-scale email sending solution using Amazon SES, Steven. I'll address your concerns regarding sending capacity and email verification.

Regarding the maximum sending speed for SES, it's important to note that Amazon SES doesn't publicly specify a maximum emails per second rate. The service is designed to scale to meet high-volume sending needs. However, new SES accounts start with sending limits that gradually increase as you demonstrate good sending practices and maintain a positive reputation.

For your requirement of sending 2 million emails per day, and potentially scaling to 5 million, you'll need to request a sending limit increase from AWS. The time to get approval for sending 5 million emails per day can vary, but AWS typically reviews such requests within a few business days. It's crucial to demonstrate a history of good sending practices and maintain low bounce and complaint rates to be approved for higher limits.

As for bulk email verification and sending from a single solution, Amazon SES itself doesn't provide a built-in bulk verification feature for recipient email addresses. SES focuses on sending emails and managing sender reputation rather than verifying recipient addresses en masse.

However, Amazon has recently introduced a new feature called SES Mail Manager, which might partially address your needs. While it doesn't explicitly offer bulk email verification, it does provide more comprehensive email management capabilities. SES Mail Manager allows you to centralize your email infrastructure, apply unified policies and rules, and manage both inbound and outbound email flows through a single interface. It also includes features for email traffic filtering and archiving for compliance needs.

To address the specific need for bulk email verification while using SES for sending, you might consider developing a custom solution that integrates SES with your own verification process. This could involve:

1. Implementing a system to collect and store email addresses.
2. Developing a verification process (e.g., sending confirmation emails, checking for syntax errors, or using other validation techniques).
3. Maintaining a clean, verified list of email addresses.
4. Using this verified list with Amazon SES for your bulk sending needs.

While this approach requires more development effort, it would allow you to keep everything within the AWS ecosystem and avoid integrating with multiple third-party providers, which seems to be a preference for your business owner.

Remember that maintaining a good sender reputation is crucial when sending high volumes of email. Amazon SES provides tools and metrics to help you monitor your sending reputation and ensure high deliverability rates. It's essential to follow best practices such as maintaining low bounce and complaint rates, authenticating your emails with SPF and DKIM, and sending high-quality content that recipients want to receive.

Lastly, consider reaching out to AWS support for personalized guidance on implementing such a large-scale email solution, as they may be able to provide more specific advice tailored to your use case and requirements.
