Up to 200,000 contacts
- Up to 200,000 subscribed contacts
- 500,000 emails a month, one pooled allowance for marketing and transactional
- 50 AI sequence generations a month

- 40 team members
- Unlimited sequences, tags and segments
- Full REST API access
- EU data residency
- Only subscribed contacts count. Unsubscribed and bounced contacts are stored free.
- Transactional email keeps flowing even when your monthly allowance is spent (fair use: up to 10% over your plan's pool).
Our infrastructure cost is driven by how much mail goes out, so that is what we size the plans around: every tier's monthly send pool is at least 2.5 times its contact cap, and sequences, tags and segments are unlimited, because building more automation costs us nothing extra and so is not metered.

Where we lose
Below roughly 1,000 contacts, Resend is cheaper than we are and ships its own automations: its marketing tier is free up to that many contacts, and its transactional tier is free for the first few thousand emails a month. Our case starts above that line. At 5,000 contacts and 25,000 emails a month, Resend is $60 across two subscriptions and Starter is €19, with the sequences, the tag schema and the drafts included.
- Customer.io, worth knowing
- Customer.io bills on peak profile count, and counts objects as well as people. Essentials includes a million emails a month, far above the scenario, and overages run $0.009 per extra profile.
- Loops, worth knowing
- Billed on subscribed contacts, with no cap on emails sent. The tier below is free up to 1,000 subscribers and the one above is $99 at 10,000.
- Mailchimp, worth knowing
- Mailchimp counts your total audience, including contacts who have unsubscribed. Standard at this tier includes 60,000 emails a month; the next contact band, 5,001 to 10,000, is $135.
- Userlist, worth knowing
- Userlist's slider starts at 10,000 users, so a 5,000-user account pays the 10,000 price. Basic includes 500,000 emails a month, visual workflows, broadcasts and transactional email; the annual price is $119.
- Brevo, worth knowing
- Brevo bills on emails per month, campaigns and transactional together, and the slider has no 25,000 step, so the scenario lands on 30,000. Starter starts at €7 for 5,000 emails but caps contacts at 500 there; marketing automation is a Standard-plan feature, which is €15 a month at 5,000 emails.
- Resend, worth knowing
- Two subscriptions: Pro covers 50,000 API emails a month for $20 and Pro marketing covers 5,000 contacts with unlimited broadcasts for $40. Under 1,000 contacts the marketing side is free and the transactional free tier covers 3,000 emails a month, which is where Resend is cheaper than we are.
- Postmark, worth knowing
- Postmark prices on emails sent and received, and the tiers jump from 10,000 for $15 straight to 50,000, so 25,000 emails a month costs the 50,000 tier. Broadcast streams share that volume; there is no contact-based pricing.
- Mailtrap, worth knowing
- Email API and Email Marketing are separate products. Basic covers 50,000 API emails for $20 (10,000 for $15, 100,000 for $30, with Business at $85 for the same 100,000). Contacts live in the marketing product, where Essential is $15 a month for 10,000 contacts and 30,000 emails, so a SaaS running both streams pays for both.
- AhaSend, worth knowing
- Transactional only: there are no contacts, campaigns or automations, so the €9 buys delivery for mail your own system composes. The next tier is €72 for 100,000 emails.
