# Warmy

> Email warm-up with seed testing, verification and DMARC monitoring

Warmy is mainly a warm-up service: domains and IPs exchange emails with a network the vendor puts at over a million real mailboxes, and a seed list of 500,000+ US inboxes opens and replies to your real sends. Every plan also includes list verification and DMARC monitoring, so it touches all three jobs, plus placement tests and an AI co-pilot. Plans are priced by warm-up volume rather than per inbox and are quoted from $49 a month.

## Key features

- **Warm-up network:** Domains and IPs warm up with real business or consumer mailboxes, sending during working hours in the recipient's time zone.
- **US seed list:** More than 500,000 US seed mailboxes, rotated monthly, open and reply to your sends and move them out of spam.
- **Verification and DMARC tracker:** List verification and SPF, DKIM and DMARC monitoring are included on every plan, with the exact record to change.
- **Adeline AI co-pilot:** Reads your tests, DNS and warm-up data and suggests what to fix; a template optimizer scores emails and rewrites parts that trigger spam filters.
- **Reputation and Postmaster data:** Tracks domain and IP reputation with blacklist alerts, and pulls Google Postmaster data in beside warm-up results.
- **API and automation:** A documented API covers every feature, with n8n, Zapier and Make for automation and a Chrome extension for checking templates.

## Good for

- Senders who want warm-up, verification and DMARC on one bill
- Ecommerce brands sending from Klaviyo, Shopify or Mailchimp
- Teams that want a named deliverability expert on the account

## Worth knowing

- The pricing page gives only a starting price of $49 a month; the real cost depends on warm-up volume.
- Plans are priced by warm-up volume, not per inbox, and team members share the plan's mailbox quota.
- The vendor lists no annual discount or plan tiers on the page; larger needs go through a demo.

## ToolGPA grades

**GPA: 2.4 out of 4**, graded Oct 18, 2026. Warmy is the one warm-up service here that also checks lists and watches DMARC on every plan, with a US seed list of 500,000+ inboxes that opens and replies to your real sends. Prices start at $49 a month and climb with volume, and the page doesn't say how far, so expect a demo before a firm number.

- **Value for money: C.** From $49 a month, priced by warm-up volume rather than per inbox, with no yearly discount listed. Among its listed warm-up rivals that's above Warmup Inbox ($15) and MailReach ($20) for one inbox but well under InboxAlly ($149), and list checks and DMARC monitoring come with it.
- **Free plan and trial: C.** No free plan, but a 7-day trial of any package with no card, and every feature is open during it.
- **Features: B.** It covers all three jobs on every plan: warm-up with business or consumer inboxes, a rotating US seed list, list checks and DMARC monitoring, plus placement tests, Postmaster data and an AI co-pilot that suggests fixes.
- **Ease of use: C.** No App Store rating on record. There's a lot to take in, from warm-up volume to DNS records and seed tests. The AI co-pilot reads your data and suggests what to fix, which helps.
- **Platforms and integrations: B.** Web and a Chrome extension, with Klaviyo, Shopify, Mailchimp, HubSpot, SendGrid, Amazon SES and Google Postmaster Tools, a documented API, and Zapier, n8n and Make. No phone or desktop app.

## Keep it, or make your own?

**Keep it.** To replace Warmy you would be making a network of real inboxes that open and answer your emails. That is not a weekend's work, with an AI app builder or without one. It costs $588 a year.

- You could not: A network of real inboxes that open and answer your emails.
- You could not: Checking that an address exists without writing to it.
- You could not: Reading the reports inbox providers send about your domain.
- You could not: It plugs into other products, Klaviyo, Shopify and Mailchimp among them, and has an API.
- You could not: AI features, unless you pay a model provider for each request yourself.
- You could not: The depth: we grade its features B, which means it covers the whole job.
