You pick the
email provider.
We do the rest.
$9/month flat. Unlimited emails. MailFlow doesn't send anything itself — you connect your own provider (Brevo, Amazon SES, Mailgun, Postmark, SendGrid, Gmail, Microsoft 365, or any SMTP). We're the platform: campaigns, audience, landing pages, automations, reports. You own the sender. Switch any time.
Every other platform owns your sending. We don't.
No surprise rate hikes
When Mailchimp bumps prices, you switch ESPs and rebuild everything. With us, you just swap the provider — your contacts, campaigns, automations, landing pages all stay.
No "your account is under review"
Send through Amazon SES in your own AWS account, your corporate Microsoft 365, or your verified Gmail Workspace. If you trust the sender, your emails go out.
No shared-IP reputation problems
Use Postmark for transactional and Brevo for marketing. Use SES with a dedicated IP for high volume. Route each campaign through whichever profile fits.
Your credentials, encrypted
AES-256-GCM at rest. The dashboard only shows the last 4 characters. We can't see them and we don't want to.
Connect one. Or all of them.
Every provider below has a real send path wired into MailFlow today — not "coming soon". Pick the one that fits your stage. Switch when you outgrow it.

One plan. Nine dollars.
No tiers, no contact-count gotchas, no "upgrade to unlock". You bring the sending provider — we bring the platform.
Pick your provider. Send your first campaign.
Sign up. The onboarding wizard walks you through connecting a sender. Import a list. Hit send. We'll show you the per-recipient log in real time.
