Frequently Asked Questions
When should I switch to a high-volume email platform? +
When you're sending 50,000+ emails per month regularly and your current platform's pricing becomes prohibitive, or you need dedicated IPs and more sending infrastructure control. Most standard platforms get expensive above 100K subscribers.
Do I need a dedicated IP for high-volume sending? +
Yes, generally. At high volumes, shared IPs are risky — other senders' behavior can affect your reputation. A dedicated IP gives you full control over your sender reputation. You'll need to warm it up gradually over 2–4 weeks before sending at full volume.
What's the cheapest way to send millions of emails? +
Amazon SES is the most cost-effective at $0.10 per 1,000 emails ($100 for a million emails). However, it's bare-bones — you'll need to build or use additional tools for templates, analytics, and list management. Brevo and Mailgun offer middle-ground pricing with more features.
