WarmySender is an outreach platform with warmup, cold email, LinkedIn, WhatsApp and a lead database from $29 a month. Warmerly is $19 a month for 5 mailboxes, with warmup on each and campaigns on the same mailboxes. Here is what each one costs and where each is ahead.

WarmySender's Pro plan is $29 a month on monthly billing for 50 mailboxes, 10,000 emails a month and 1,000 email verifications. Warmerly Starter is $19 a month for 5 mailboxes with no cap on sends. WarmySender's yearly price for Pro is $13.05 a month, so it is the cheaper of the two once you pay up front or run more than 5 mailboxes. They are not the same kind of product.
Warmup on every mailbox, SPF, DKIM and DMARC checks every six hours, and campaigns from the same mailboxes. LinkedIn is $19 per account on top.Free plan with no card, or a 7-day trial on paid plans, which needs a card.

WarmySender and Warmy are two different companies. WarmySender's own page says it is separate from Warmy.io, an email warmup tool, and we have no reason to doubt that. If you came here looking for Warmy's pricing, see Warmerly against Warmy; Warmy's page was read on 22 October 2026 and starts at $49 a month. Warmerly against Warmy.
WarmySender sells a bundle. The page calls it an outreach platform: cold email with multi-step sequences, A-Z testing of up to 26 variants and conditional branching, email warmup, LinkedIn and WhatsApp campaigns, email verification, and a B2B contact database. It also puts an AI agent at the centre of the product, one you connect through MCP, which builds and launches campaigns while WarmySender's own scheduler paces the sending within per-account caps. Warmerly is narrower on purpose. It warms mailboxes, checks their DNS records every six hours, rescues warmup mail from spam, and sends email and LinkedIn campaigns from the same mailboxes.
On warmup, the two describe different things. WarmySender says warmup is peer-to-peer between real business mailboxes in its network, that each message is composed fresh, that conversations run up to five replies deep, that placement is checked the next day, and that a mailbox's volume drops at around 5% spam placement and the mailbox is taken out of the pool past roughly 15%. Those are its own statements, not measured by us. What it does not publish is how many warmup emails a mailbox sends a day. Enterprise and Ultimate say unlimited warmup, and the page never defines unlimited. If warmup volume matters to you, ask in writing before you pay. Warmerly publishes the number: a mailbox starts at 4 a day, reaches 25 a day by day 14 and 50 a day by day 30, with Gmail held to 40 and Outlook to 30.

Headline prices for the same number of mailboxes, on monthly billing unless stated. WarmySender is cheaper from 6 mailboxes up. The price per mailbox is not the whole picture: Pro caps email at 10,000 a month, and its page gives no warmup limits to set against Warmerly's published ramp.
| Scenario | Warmerly | WarmySender |
|---|---|---|
| 5 mailboxes | Starter, $19 a month. | Pro, $29 a month, or $13.05 billed yearly. |
| 25 mailboxes | Growth, $49 a month. | Pro, $29 a month, or $13.05 billed yearly. |

| 100 mailboxes | Agency, $179 a month. | Enterprise, $69.99 a month, or $31.49 billed yearly. |
| A year on the smallest plan that fits 5 mailboxes | $190 on Starter, billed yearly at ten times the monthly price. | $156.60 on Pro billed yearly, or $313.20 once for three years. |
| One LinkedIn account on top | $19 a month. | $12 a month, or $120 a year. |
Billing is where WarmySender needs a careful read. Its prices come in three bands: monthly, yearly, and a 3-year prepayment paid once. The yearly Pro price of $13.05 a month and the 3-year price of $8.70 a month are real, but they are what you pay for committing, so the fair comparison is Pro at $29 against a Warmerly plan on monthly billing. The page also says its annual discount is evergreen even though it is shown with an end-of-month countdown, and it shows a one-time $9 a month Pro price to new accounts for a 15-minute window. We would ignore the countdown and decide on the listed prices.
Refunds are narrow. WarmySender refunds in full within 7 days of a payment, provided the account has not been used to send campaign or warmup emails, LinkedIn or Instagram actions, or to spend lead or verification credits, and lead and verification credits are not refundable to the card. In practice that means you cannot test warmup for a week and then claim your money back. Warmerly's free plan covers one mailbox with no card, which is the cheaper way to test; paid plans have a 7-day trial that needs a card, and payments already taken are not refunded, with named exceptions.
WarmySender read on warmysender.com/pricing, 24 October 2026. Yearly Warmerly price is ten times the monthly price. Free sends are capped, and warmup is capped at 50 a day per mailbox by day 30.
The table above, sorted. Where nobody is ahead, or the pages do not say, the row is left out of both lists.
WarmySender suits someone who wants one low-priced tool for lead data, email and LinkedIn and is comfortable asking support what its warmup limits are. Warmerly suits someone who wants the bill and the warmup ramp stated before they start, and warmup and campaigns on the same mailboxes. Our reading of the facts above, not the only reasonable one.
Per mailbox, with no DNS changes. Reputation lives at Gmail and Microsoft, not inside either tool, so moving a mailbox does not reset it. Run Warmerly on one mailbox first and compare before you cancel anything.
Warmup from two tools on one mailbox doubles its daily volume, so choose a mailbox and pause WarmySender's warmup on it first.
Connect Gmail or Google Workspace with an app password, or sign in with Microsoft 365. The Free plan takes 1 mailbox and needs no card.
Daily volume grows each day. A Gmail mailbox is held to 40 a day and an Outlook mailbox to 30; the ramp reaches its ceiling by day 30.
Connect a mailbox. Warmerly runs alongside whatever you use now, so you can compare placement side by side before you move anything.
Free plan, no card. Paid plans: 7-day trial with a card, first charge on day 8.
