Frequently asked questions

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

How long should I warm a mailbox? Roughly two weeks for a new address, longer for a brand-new domain, and keep it on afterwards. Warmup 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

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.

Is sending metered? Not on paid plans. See plans and limits for what actually bounds your volume.

What does LinkedIn cost? $50/month per connected account, separate from your plan, no trial.

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

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 allowance is only debited when the action actually returned a result.

How do I cancel, change my card, or get an invoice? Settings > Billing > Manage billing opens the Stripe portal, which owns all three.

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

Warmerly says my DKIM is missing but it is configured. That is almost always a custom selector Warmerly could not guess. Fix

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

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 live probe that sends real email from your mailbox to seed addresses across providers and reports inbox vs promotions vs spam. Each run spends one of your monthly placement tests. More

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

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

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

Are replies separated from warmup traffic? Yes. Warmup mail is classified separately, and real replies are auto-sorted into leads, not-relevant and spam. Inbox API

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

API and integrations

Which plan has API access? Agency. Authentication

How do I authenticate? An X-Api-Key header, plus X-Project-Id to say which project you are acting in. Authentication

Are there rate limits? Yes, per endpoint group, and they are separate from your plan's monthly allowances. Errors and rate limits

Can I get notified instead of polling? Yes - subscribe to outbound webhooks for mailbox health events. Webhooks

The app itself

Is there a mobile app? Yes, an Android app covering accounts, campaigns, leads and Warmi support chat. 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
