New: Retry to Send to Failed Recipients
What’s New
We’ve introduced a retry feature for newsletter campaigns that have partially failed to send. If certain recipients did not receive the newsletter due to sending restrictions or other errors, you can now resend only to those failed recipients — rather than resending the entire campaign to everyone.
Why This Matters
- SMTP Rate Limits: Some SMTP providers place limits on how many emails can be sent within a specific timeframe (for instance, 50 emails/hour). This can lead to a situation where some emails in a batch are not delivered.
- Selective Resending: Instead of duplicating emails to all recipients (which risks confusion and spam complaints), this feature targets only failed addresses, reducing the chance of sending duplicates.
- Efficiency & Control: You maintain tighter control over your email campaigns by spotting and fixing deliverability issues without restarting the entire campaign.
How It Works
- Identify Failed Recipients: When a newsletter sending job finishes, you’ll see if there are any failed deliveries.
- Initiate Retry: In the newsletter overview or campaign details, look for an option labeled “Retry Sending failed emails.
- Confirm & Send: Choose to resend only to those failed addresses, preserving your main email campaign report and statistics.
Availability
This feature is exclusive to companies using their own SMTP service for email delivery. If you use myflow’s mail servers, the retry feature will not be available.
Additional Notes
- Provider Requirements: Be aware of your SMTP provider’s rate limits and any additional restrictions that may lead to throttling or blocking.
- Best Practices:
- Verify your domain’s authentication (SPF, DKIM, DMARC) to improve deliverability.
- Use clear consent forms and avoid sending duplicate newsletters within short timeframes to reduce spam issues.
By using the new retry feature, you can streamline your newsletter campaign management, tackle partial send failures more easily, and reduce the risk of unintentionally bombarding your mailing list.
