If your mailbox warmup was disabled due to a bounce, here's what you need to know and how you can safely resume the process to ensure optimal deliverability with Smartlead.
Why Did This Happen?
To maintain the highest standards of deliverability across our rapidly growing warmup pool, we’ve several rigorous checks in place:
Email Validation Every 6 Hours: We validate all addresses in the warmup pool to ensure they’re valid.
Try-Catch Validation: If an email fails the initial check, we run it through a slower try-catch mechanism for deeper verification.
6-Step SMTP Verification: Addresses that fail the try-catch step undergo a thorough 6-step SMTP check to confirm validity.
This multi-layered process ensures only high-reputation domains remain in the pool, protecting its integrity and improving deliverability.
Take this as an opportunity to review your setup. Resolve any configuration issues, verify your email lists, and ensure your domain settings (like SPF, DKIM, and DMARC) are properly configured.
