Frequently Asked Questions

What is email warmup and why is it important?

Email warmup gradually builds your sender reputation by slowly increasing email volume over time. This prevents spam filters from flagging your domain as suspicious. Before starting, verify your email authentication with SPF Checker and DMARC Lookup to ensure maximum deliverability.

How long should email warmup take?

Warmup duration depends on domain age and strategy. New domains should use conservative warmup (30-45 days), while established domains can use moderate approach (20-30 days). Monitor your campaign performance on Dashboard and compare email server performance on VPS benchmarks.

What if my emails still go to spam after warmup?

First, check if your domain is blacklisted using Blacklist Checker. Verify DNS records with DNS Lookup and ensure SPF, DKIM, DMARC are properly configured. Review email content quality and reduce sending volume by 50% until engagement improves.

Can I use this for transactional emails?

While this tool focuses on cold email campaigns, transactional emails also benefit from proper warmup. For high-volume transactional email needs, consider dedicated email servers with proper infrastructure. Compare VPS hosting options optimized for email delivery or browse VPS providers with excellent email deliverability records.
