Set up, manage, and troubleshoot MailboxWarm.

Save addresses, edit schedules, and explore sandbox billing.

Provider connections and live warming are not available yet. Saving an address does not connect it, verify ownership, or send email. The dashboard checks current availability before offering a provider action. Never enter live payment details into Stripe sandbox.

App sign-in and mailbox authorization are separate.

Google setup uses an App Password with fixed SMTP and IMAP endpoints over TLS; both checks must pass. Microsoft uses account authorization and may require administrator consent. Generic SMTP setup checks your provider’s sending endpoint over TLS; it does not connect your inbox through IMAP. Follow the provider-specific setup guide when connections become available. Do not share passwords or verification codes with support.

Set the starting volume, target, timezone, and sending hours.

Open the mailbox, then Warming settings. The initial volume must not exceed the target, and the end time must be later than the start time. Overnight windows are not supported. Your paid mailbox allowance and provider limits still apply. Save settings and look for the saved confirmation. Saving does not start warming.

No. Activity and subscription renewal have separate controls.

Pause stops warming while keeping the mailbox’s schedule. To stop billing for a mailbox at its next renewal, open Billing and cancel renewal for that named address. Current paid access continues through its paid-through date. Other mailboxes keep their own renewal settings. Canceling renewal is not account deletion.

Upgrade after payment. Lower tiers and annual-to-monthly switches start at renewal.

Each mailbox has its own subscription and billing dates. Upgrades within the same billing frequency charge the difference for the remaining paid time and keep your renewal date. Switching from monthly to annual on the same or a higher tier charges the annual price minus unused paid monthly time and starts a new annual term. Lower tiers and all annual-to-monthly changes start at renewal, with nothing due now. During a trial, upgrading charges the selected plan’s full price and ends the trial today. Review the amount and date before confirming. Undo a scheduled change before upgrading. If payment is pending, complete or cancel that payment instead of starting another. Other mailboxes are unaffected.

Submitted, observed, rescued, read, and replied are separate events.

A submission is not proof of delivery. Initial observed placement is recorded before seed-side interactions; missing observations remain unknown. A read flag is not proof of a human open. Private seed observations do not guarantee inbox placement for other recipients. Simulated events are labeled and are not live deliverability evidence.

Check the date range, mailbox readiness, and current availability.

Clear activity filters or choose a wider date range first. Then open the mailbox and check its connection, paid access, warming state, timezone, and sending window. A paused mailbox does not start merely because its settings were saved or its plan was paid. Live warming is unavailable in this preview. An empty history means no recorded events in that scope, not a zero inbox rate. If the page is offline, reconnect and refresh before interpreting cached results.

Retry safely without sharing credentials or repeating payments.

Use the account email and the most recent verification code. Check spam if a code does not arrive. A temporary service or network failure is different from an expired session: reconnect and retry. For billing, check the pending request before paying again. When reporting a problem, describe the page, action, time, and visible error. Never include passwords, codes, card details, or unredacted mailbox screenshots.
