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.
- 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.
