Send volume
Providers charge by monthly email volume. A plan's included volume and overage rate matter more than a headline price.

How this email pricing calculator works
Choose your monthly send volume. We calculate the lowest public self-serve plan for each provider, including the plan minimum and documented overage. The result updates instantly.
All prices are monthly USD list prices. Free tiers are listed separately, so you can see whether a provider covers a small workload before paying for a plan.
What determines your monthly email bill
Plan minimum
Many providers have a minimum monthly plan. At low volume, the plan minimum can cost more than the emails you actually send.
Features and add-ons
Dedicated IPs, validation, inbound email, extra retention and annual billing can change the final invoice. This calculator excludes them.
Free tiers and plan minimums
Free quotas range from 100 emails per month to 3,000 per month, or a one-time 10,000-credit balance. The all-provider table shows each free allowance next to its paid estimate. Amazon SES has no permanent free tier, but new accounts may receive $200 in credits.
Per-address gateways: route billing@ through Postmark for deliverability and notifications@ through SES for cost, with overflow if one provider fails. You do not have to choose one provider for every message.
Frequently asked questions
How is the monthly price calculated?
We take the cheapest public self-serve plan that covers your selected volume, or add the provider's documented overage rate when that is cheaper. Taxes, add-ons, annual discounts and custom plans are not included.
Are free tiers included?
Yes. Every provider row shows its free quota. Some are monthly, some are daily, toSend offers a one-time credit balance, and Amazon SES currently has no permanent free tier.
Why is the cheapest provider not always the best choice?
Price is only one factor. Deliverability, regions, inbound support, retention, support and compliance can matter more for production email.
How does SenderFly lower email costs — without forcing you onto one cheap provider?
SenderFly sits between your app and the providers you connect (BYOK). You do not have to pick one: • Per-address gateways — route billing@ through Postmark for deliverability while notifications@ goes through SES at $0.10/1k. • Cheapest, failover, round-robin or primary/backup — choose a strategy per route, with no application code changes. • Automatic spillover — when a provider fails or throttles, SenderFly moves the message to the next one. Keep the cheap rate where it is safe and the reliable sender where it matters, instead of overpaying one provider for everything.
Are prices in USD and do they include tax?
Yes, estimates are monthly USD list prices and exclude taxes, add-ons, annual discounts and custom plans. Check the official source link for the latest quote.
How often are prices updated?
We checked all prices on 2026-10-26 against official public pricing pages. Providers can change prices at any time; use the source link on each row to verify before purchasing.
