Questions
- What counts as a send?
- One email to one subscriber. A campaign to 1,000 people uses 1,000 emails. Subscribers are always free and unlimited.
- Do unused emails roll over?
- No. Your allotment resets each billing period. Pick the plan that fits your rhythm; change it whenever.
- What happens if I go over?
- You can't. Sending pauses cleanly at your cap, with no surprise charge. Need more room? Move up a plan in a couple of clicks.
- Can I try it before I pay?
- Yes, properly. Signing up is free: connect your domain, import an audience, write a campaign, and send it for real. Sandbox mode covers up to 100 emails a month to your own team's addresses, through the same pipeline with the same tracking, so you can see the thing arrive before you pay for anything.
- Is there a free tier?
- Yes, and it isn't silent. It sends in sandbox mode, 100 emails a month to your own organization's members. What a paid plan unlocks is mailing everyone else, from $1/mo. You can integrate the transactional API and rehearse a whole migration without a card.
- Is the AI writing assistant included?
- Yes, on every paid plan, from $1/mo. Draft from a brief, get subject lines, rewrite highlighted copy. Bigger plans carry a bigger AI allowance, but none of them are without one.
- Do automations cost extra?
- No. Build as many automations as you like and run them for as many people as you like, on every plan including free. The only thing metered is the emails they send, which come out of the same monthly allowance as campaigns.
- What if I send more than a million emails a month?
- Get in touch. The self-serve ladder tops out at 1,000,000 emails for $220/mo; above that we set the plan up with you directly.
Set up free. Pay when you send.
