The Warmy email deliverability test: a seed list, and a quota per plan
After the warm-up, Warmy is best known for its deliverability tester. You send an email to its seed addresses, and the report shows, provider by provider, whether it reached the inbox or the spam folder, with authentication checks and blacklists alongside.
How many tests each plan includes
Warmy’s comparison pages give each plan a monthly allowance: 5 on Starter, 10 on Business, 25 on Premium, 50 on Expert and 50 on Platinum. The allowance is shared by every mailbox on the account rather than given to each one, and the pricing page asks you to confirm it with the Warmy team. The page of its free test goes further, offering “unlimited inbox placement tests” through sales: the quota depends on the page you read.
The free version, without an account
Anyone can run a basic test on warmy.io without signing up: it reports placement by provider and checks the sending IP against blacklists. The paid tests use a list of US seed addresses that Warmy refreshes every month; a separate list of consumer mailboxes, for B2C senders, is priced only inside the app.
Emelia and placement tests
Emelia does not run inbox placement tests. For each mailbox its plan connects, it runs the warm-up, gives a health score and checks the MX, SPF, DKIM and DMARC records.
Warmy on Capterra, G2 and Trustpilot: three different scores
Review sites rate Warmy well, though not equally. G2 and Capterra block automated reading, so their figures come from search results read in October 2026; Trustpilot was read directly.
Where the scores agree
- Capterra and G2 both rate it near the top of the scale: 4.9 and 4.8
- 62% of its Trustpilot reviews give five stars
- Its Chrome extension, Email Template Checker, averages 5.0 from 34 ratings
Where they part ways
- Trustpilot’s score is lower, 4.0, with 11% one-star reviews
- Warmy’s site says “4.9/5 on G2”; search results for G2 show 4.8
- G2’s review count changes from one of its pages to another
The Warmy API and AI Connect
Warmy publishes a REST API with “90+ documented endpoints” across “20+ resource groups”, plus webhooks, and its OpenAPI specification is readable without an account. It covers mailboxes (creation, settings, status), domains, seed lists, tests, groups and reports, at up to 60 requests a minute. Creating a mailbox requires a plan identifier, and another endpoint moves a mailbox to a different plan: in the API too, plans are attached mailbox by mailbox.
Its pages disagree on access. The documentation has you generate a key in the workspace settings, and a directory entry says full API access comes with every plan; the API page itself asks you to schedule a short call first. AI Connect adds MCP connections so that assistants such as Claude or ChatGPT can work with your Warmy account; it also starts with a demo. The integrations page counts 229 connections, among them sending tools such as Instantly, lemlist and Smartlead, whose mailboxes Warmy can warm.
Emelia’s API is part of every plan as well (100 requests a minute on Start, 300 on Grow): it switches warm-up on or off and reads each mailbox’s warm-up status and score, as it does for campaigns and contacts.
A plan per mailbox, or one plan for several?
Warmy’s pricing page shows one figure, plans “starting from $49 / month”, and calls its pricing volume-based. Its comparison pages list 5 plans, from Starter at $49 to Platinum at $429 a month, each said to cover multiple mailboxes, with no number given.
The product tells another story: in the app and the API, each mailbox carries its own plan, and Warmy’s blog writes “$49/mailbox/mo”. We count one Starter plan per mailbox; the Warmy pricing page lays out the sources and the bill for any number of mailboxes.
Warm-up alone, or warm-up inside a sending plan: Warmy and Emelia
The rows start from Emelia’s plans, Start for up to 3 mailboxes and Grow for up to 50, with Warmy’s bill for the same mailboxes beside them. Warmy’s price buys warm-up, tests and monitoring; Emelia’s also sends the campaigns. In euros, a row names the cheaper side only when that holds at any exchange rate.

What Warmy looks like
Experts, 24/7 support and free migration
Warmy sells guidance as much as software. Every account has a deliverability expert, human support answers around the clock by chat, email, WhatsApp and video, weekends included, and the Expert and Platinum plans add a dedicated customer success manager and consultant. Moving from another warm-up tool costs nothing: its team transfers your mailboxes and settings.
Agencies get a dashboard and client workspaces on every plan, with as many users as they like, all sharing the mailboxes of the subscription. The white-label option is gone: Warmy’s blog says it was discontinued in 2026.
The company behind it, Warmy Technologies LTD, is based in Tel Aviv and was founded in 2021 by Daniel Shnaider and Michael Shnaider. Its About page counts 120 team members (85 in a press release from October 2025). The number of customers it claims depends on the page: “7,000+” businesses on the pricing page, “35,000+” on the home page.
Warmy: signing in, the extension, campaigns and replacements
The app is at app.warmy.io: the “Sign In” button on warmy.io opens that sign-in page, where you use your email and password or continue with Google. Warmy’s help centre says two-factor authentication is not available yet; its security page offers SSO and two-factor authentication for enterprise workspaces only.
Email Template Checker, Warmy’s free extension, scores an email while you write it: links, formatting and the words that tend to trip spam filters, summed up in a risk score. It has about 475 users on the Chrome Web Store. Emelia’s Chrome extension serves another purpose, on LinkedIn: on a profile it finds the person’s email and phone number (paid in credits, only when found) and adds them to a campaign, and in Sales Navigator its “Export with Emelia” button sends a search to Emelia, which extracts the leads.
No. Warmy describes itself as built only for deliverability: you keep sending from your own tool and connect the same mailboxes to Warmy. SendNova, still in beta, reads the activity of campaigns sent through services such as Mailgun or SendGrid, and the sequence builder on its site is a free writing aid. Emelia sends the campaigns from the mailboxes it warms.
