Sending limits
Faivelo’s sending limits are layered: your plan sets a monthly quota, and your account carries a daily allowance that starts conservative and grows automatically as your clean sending history builds. Limits are the reason mail sent through Faivelo lands in the inbox — mailbox providers trust senders who ramp up, and distrust ones who blast. The full rules live in the Sending Policy; this page explains how they work day to day.
Monthly quotas by plan
Transactional (API) mail and campaigns have separate budgets — a newsletter can never eat into your app’s password resets. Everyday mail from webmail or your own mail app is never metered.
| Plan | Transactional / month | Campaigns / month | API rate |
|---|---|---|---|
| Free trial | 100 | 100 | 10/min |
| Starter | 500 | — | 10/min |
| Growth | 10,000 | 3,000 | 30/min |
| Pro | 100,000 | 25,000 | 60/min |
| Business | 250,000 | 100,000 | 120/min |
Quotas reset on the 1st of each calendar month. Unused sends don’t roll over. Campaigns also have per-campaign size caps (Growth 3,000 · Pro 15,000 · Business 25,000 recipients). (The Free plan is forwarding-only and doesn’t include sending.)
Sending domains and warm-up
Receiving is unlimited everywhere, but sending happens from domains you designate (Starter/Growth 1, Pro 3, Business 10 — the domain page has the switch; your first verified domain is designated automatically). A newly designated domain warms up: it starts at 200 recipients a day and the ceiling doubles every clean week until it clears your plan’s caps. A hard bounce restarts the climb. While a domain is warming up, the first 200 recipients of each campaign go out as a canary — if they bounce badly, the campaign pauses itself before the rest sends.
The earned account allowance
On top of the domain ramp, every account has a daily (and hourly) allowance that works like a credit limit:
- New accounts start small — around 50 emails on day one, paced through the hour.
- Clean sending raises it automatically. No forms, no waiting on support, no manual reviews. Typical business volumes unlock within the first few weeks; the largest allowances build over the first months. You get a notification each time your allowance increases.
- Bounces slow the climb. A hard bounce resets your clean streak; consistently clean sending is the only thing that speeds it up.
This is the same warm-up discipline every serious email provider uses. If you genuinely need more than the allowance grows to — validated bulk sending at real volume — contact support@faivelo.com and talk to us rather than trying to work around it.
Cold outreach: per-mailbox caps
Cold outreach campaigns have their own per-mailbox daily caps with built-in warm-up: new senders start at 20 emails/day, rising to 35/day after one week and 50/day after three weeks, with sends paced through the day like a human sender. The campaign wizard shows an honest estimate of how long your list will take before you commit. See the Sending Policy for the full outreach rules.
Automatic protections
A few guardrails act on their own, because reputation damage can’t be undone after the fact:
- Suppression list. Addresses that hard-bounced or complained are dropped from every future send automatically — they never count against you again, and they never bounce against your reputation twice.
- Bounce protection. A burst of hard bounces in a short window pauses your sending. You’re warned by email before enforcement, with the exact numbers. An honest sender with the occasional bad address never gets near this; a purchased list trips it in the first minute.
- List-quality gate. If more than 5% of a campaign list is undeliverable, the campaign is refused outright — that failure rate is the signature of a purchased or scraped list.
- Campaign kill switch. An outreach campaign whose deliveries start failing (over 3%) pauses itself and tells you why.
If your sending is paused and you believe it’s a mistake, contact support@faivelo.com — a human reviews every appeal.
What counts as a send
One recipient = one send. A campaign delivered to 500 addresses uses 500 sends, regardless of how many campaigns you split them across. The same is true for cc and bcc on API sends.
Things that do not count against your quota:
- Suppressed addresses that Faivelo skips automatically (they’re never sent)
- Regular day-to-day mail you send from your mailbox through an email app or webmail
One shared pool
Campaign sends, transactional API sends, and AI-agent sends via MCP all draw from the same monthly quota and the same daily allowance. If your tools and your campaigns both send from the same account, budget accordingly.
What happens when you hit a limit
- Starting a new campaign is blocked with a clear error telling you how many sends you have left and which limit you hit.
- A campaign already in progress is paused automatically. Nothing is lost — the remaining recipients stay queued, and it resumes when the limit resets or your plan changes.
- API sends are rejected with the same limit information — monthly and daily limits are named separately, so your code can tell “wait until tomorrow” from “upgrade or wait for the 1st”.
Faivelo checks quotas continuously during a campaign, not just at the start, so you’ll never accidentally overshoot.
Where to see your usage
Open the Metrics page in your dashboard. It shows how many sends you’ve used this month, your plan’s limit, and what’s remaining.
Need more sends?
Upgrade at any time from the Billing page — the higher monthly quota applies immediately, and upgrades are prorated. The earned daily allowance is not tied to your plan: it grows with history, on every plan. See Billing & plans for a full comparison.
