## Warmup

**Does warmup send email to my prospects?** No. Warmup traffic goes only between mailboxes inside Warmerly's private warmup network, in both directions. Your lists are untouched until a campaign sends. [How warmup works](https://warmerly.com/docs/how-warmup-works)

**How long should I warm a mailbox before sending?** You don't have to wait: a campaign on young mailboxes (under 14 days of warmup) starts slowly by itself (3 emails per mailbox on day one, climbing) so you can launch today. A mailbox's first two weeks are its warming period and its warmup volume keeps rising until about day 30, longer on a brand-new domain. Keep warmup on afterwards; it is maintenance, not a one-off setup step.

**Can I skip warmup if my mailbox is old and already in use?** You can, but an established mailbox has reputation for its *existing* sending pattern. Outbound campaigns are a new pattern, and ramping into them is what stops providers treating the change as suspicious.

**My warmup reply rate is 60% but my campaign replies are near zero. Why?** Those are two unrelated metrics with similar names. The warmup figure measures activity inside the warmup network; the campaign figure measures real people. [The difference](https://warmerly.com/docs/how-warmup-works)

**Does it matter who hosts my mailbox?** No. The warmup network spans many providers, so Gmail, Outlook and others see the activity regardless of where your sending address is hosted.

**Is warmup included in my plan?** Yes, on every plan including Free, and it is never metered. What limits warmup is how many mailboxes your plan lets you connect.

## Plans and billing

**Is Free a trial?** No - no card, no expiry, stay as long as you like. Paid tiers separately include a 7-day free trial, which does need a card and charges nothing until day 8.

**Do you have a startup program? (Warmerly for Startups)** Yes. Companies founded in the last 3 years that have raised under $5M in total, and are not lead-generation agencies or resellers, can apply at [warmerly.com/startups](https://warmerly.com/startups). The program is only for people who do not have a Warmerly account yet, and each company website can apply once. Accepted startups show a small Warmerly badge, linked to warmerly.com, on their website, and we check it is live before the place is confirmed. Approved startups get the Growth plan at 50% off for 12 months: $24.50/month, then the normal $49/month. They pay from the first day, with no free trial. A person reviews every application; once the badge is confirmed, an email links to **Settings > Billing** to activate it. A card is needed to activate and is charged the discounted price straight away, and there is no code to enter.

**What is the 30-day free trial offer?** Visitors who claim it on warmerly.com get 30 days free on any paid plan instead of 7. A card is needed at checkout and the first charge is on day 31. It must be used within 14 days of creating the account, once per account, and the billing page always shows the trial length that applies to you.

**Is sending metered?** Not on paid plans. See [plans and limits](https://warmerly.com/docs/plans-and-limits) for what actually bounds your volume.

**What does LinkedIn cost?** It is billed per connected account each month, separate from your plan, with no trial. The current price is on [warmerly.com/pricing](https://warmerly.com/pricing).

**What happens when I hit a limit?** The action is refused with an explanation, and nothing is deleted. Going over your plan overall gives you a grace period, then sending and warmup pause until you are back inside it or upgraded. [Details](https://warmerly.com/docs/plans-and-limits)

**Do unused monthly allowances roll over?** No. Verifications, lookups, exports, placement tests and AI credits reset on the 1st.

**Am I charged for a lookup that finds nothing?** No. An email lookup is only counted when it finds an address, and an action that fails with an error is not counted. A fresh verification result is counted; one Warmerly already remembers is not.

**How do I cancel, change my card, or get an invoice?** **Settings > Billing > Cancel plan** cancels your plan. **Settings > Billing > Manage billing** opens the Stripe portal, where your card and invoices are.

**Can support change my plan for me?** No - plan changes are always yours to make, with your own card, at **Settings > Billing**. Warmi can read your plan and usage but has no ability to change either.

## Mailboxes and deliverability

**How many mailboxes do I need?** Work back from volume: mailboxes x daily limit (30/day by default). For 300 sends a day you want about ten warm mailboxes, not one mailbox pushed ten times as hard.

**Do I have to set up DKIM, SPF and DMARC?** Yes, for anything you intend to send at scale. They are the difference between delivered and spam before your copy even gets read. [Guides](https://warmerly.com/docs/guides)

**Warmerly says my DKIM is missing but it is configured.** That is almost always a custom selector Warmerly could not guess. [Fix](https://warmerly.com/docs/troubleshooting)

**My Microsoft 365 mailbox reconnected but sending fails with a password error.** Usually a mailbox-identity mismatch or tenant-disabled SMTP AUTH, not a wrong password. [Fix](https://warmerly.com/docs/troubleshooting)

**Can I use a shared or alias mailbox?** Yes, with the SMTP/IMAP username set to that mailbox's own address, provided the signed-in account has Send As or Full Access rights.

**What is a placement test?** A probe that sends real email from your mailbox to test mailboxes and reports inbox vs promotions vs spam. If no seed mailboxes at the big providers are available, it tests against Warmerly's own warmup mailboxes and the result is labelled as limited accuracy. Each run spends one of your monthly placement tests. [More](https://warmerly.com/docs/troubleshooting)

## Campaigns, leads and inbox

**My campaign is not sending.** There is an ordered checklist for this - status, mailboxes, daily limits, schedule, billing state, suppression. [Work through it](https://warmerly.com/docs/troubleshooting)

**Can two campaigns share a mailbox?** Yes, and they share that mailbox's daily limit rather than each getting a full one.

**What does "active prospects" mean?** Unique people across your active and paused campaigns, counted workspace-wide - distinct from the per-campaign lead ceiling.

**Can I bring my own leads?** Yes, by import, and Warmerly also has its own company and contact database you can search and pull from, metered as lead exports. [Leads API](https://warmerly.com/docs/leads)

**Does Warmerly verify addresses before sending?** Verification is its own tool with its own monthly allowance, and it is worth running on imported lists - bouncing a bad list is one of the fastest ways to damage a mailbox you spent weeks warming. [Verify API](https://warmerly.com/docs/verify)

**Are replies separated from warmup traffic?** Yes. Warmup mail is kept out of your inbox view and never graded. Replies from people who are leads in your campaigns are sorted into Interested, Not relevant and Spam; other mail stays Unclassified and shows only under **All**. [How the Inbox works](https://warmerly.com/docs/help/inbox) · [Inbox API](https://warmerly.com/docs/inbox)

**How do I make sure someone is never contacted again?** Add them to the suppression list; suppressed addresses are never sent to by any campaign. [Suppression](https://warmerly.com/docs/suppression)

## API and integrations

**Which plan has API access?** Agency. [Authentication](https://warmerly.com/docs/authentication)

**How do I authenticate?** An `X-Api-Key` header, plus `X-Project-Id` to say which project you are acting in. [Authentication](https://warmerly.com/docs/authentication)

**Are there rate limits?** Yes, per endpoint group, and they are separate from your plan's monthly allowances. [Errors and rate limits](https://warmerly.com/docs/errors)

**Can I get notified instead of polling?** Yes - subscribe to outbound webhooks for mailbox health events. [Webhooks](https://warmerly.com/docs/webhooks)

## The app itself

**Is there a mobile app?** Yes, an Android app covering accounts, campaigns, leads and Warmi support chat. It also has an inbox with your replies, and sends a push notification when a genuine reply arrives (warmup traffic never notifies). [Android app guide](https://warmerly.com/docs/help/android-app) · [warmerly.com/android](https://warmerly.com/android)

**Who is Warmi?** The assistant in the chat widget. Warmi searches these docs in front of you, can read your own mailbox, campaign, plan and usage data when you are signed in, and can hand a conversation to a human. Warmi cannot change your billing or your plan - by design, there is no tool for it.

**Can I manage several clients in one account?** Yes. Projects separate clients or brands inside a workspace, each with their own mailboxes, campaigns and inbox. [Workspaces and projects](https://warmerly.com/docs/workspaces)
