How to Send 100,000 Emails Weekly Without Encountering Delivery Issues

Sending large quantities of emails weekly can present significant challenges, particularly in ensuring their successful delivery. While DIY solutions are possible, they require considerable technical expertise and may ultimately prove impractical.

Outsourcing for Simplicity and Cost-Effectiveness

The most straightforward and cost-effective approach is to outsource email delivery to specialized companies. This eliminates the need for in-house infrastructure and the complexities associated with maintaining email deliverability.

DIY Considerations for Self-Hosting

If outsourcing is not feasible, consider the complexities involved in self-hosting an email sending system:

Infrastructure and Technical Requirements:

• Dedicated SMTP server with sufficient capacity to handle the volume
• Configurable SMTP wrapper to send emails efficiently
• Custom sender function to process and send emails
• Sufficient virtual memory to avoid PHP memory limits

Delivery Optimization:

• Shuffle email delivery to avoid server bans
• Establish proper PTR, SPF, DKIM records
• Handle remote server timeouts and other network issues

Content and Compliance:

• Create non-spammy content that stands out from actual spam emails
• Handle invalid email addresses and maintain a clean subscriber list
• Manage unsubscribes to prevent users from marking emails as spam
• Handle email bounces and rejects effectively

Legal Implications:

• Comply with federal, state, and local anti-spam regulations
• Consider the impact of sending emails to recipients in different countries

Additional Considerations:

• Handle the delays inherent in SMTP protocol
• Mitigate the risk of emails being flagged as spam
• Address issues related to various email clients, particularly Microsoft Outlook

Conclusion:

While it is technically possible to self-host an email delivery system for large volumes, the complexities and difficulties involved make it a challenging and potentially time-consuming endeavor. Outsourcing remains the most practical and cost-effective solution for ensuring successful and compliant email delivery.
