lemwarm alternatives: warm-up alone or built into a sending tool

lemwarm charges $29 per address a month to warm a mailbox, and stops there. Its alternatives come in two families: sending tools that warm your mailboxes as part of the plan, and other warm-up-only tools, each billing in its own way. Here are 10 of them, Emelia included, grouped by the need they answer, with prices checked in October 2026.

Warm-up that comes with the sending tool: Emelia, lemlist and Instantly

When the mailbox you would warm with lemwarm sends its campaigns from another tool anyway, these three do both jobs under a single subscription.

  1. 1

    Emelia

    Best for: Warm-up, cold email and LinkedIn in one plan

    Each plan connects a set number of mailboxes and warms every one of them: up to 3 on Start with 1 LinkedIn account, up to 50 on Grow ($97 a month, 3 accounts), unlimited on Scale. Campaigns go out from the same mailboxes and the email finder is in the plan. There is no free tier: Emelia asks for a paid plan and sets sending limits, which keeps its warm-up network clean.

    From $37/month
  2. 2

    lemlist

    Best for: Keeping lemwarm, with lemlist doing the sending

    lemwarm Essential is part of every paid lemlist plan, so moving your campaigns to lemlist removes the separate warm-up bill. Email costs $69 a month for the whole team, with as many addresses as you connect and up to 50,000 emails a month; Multichannel adds LinkedIn at $109 per user a month. Inbox placement tests sit in its Deliverability Hub, paid in credits.

    From $69/monthlemlist
  3. 3

    Instantly

    Best for: Cold email billed by volume, warm-up included

    Instantly bills emails and contacts rather than mailboxes: Growth costs $47 a month for 5,000 emails and 1,000 contacts, with as many mailboxes as you connect and their warm-up included, after a 14-day trial without a card. It does not automate LinkedIn.

    From $47/monthInstantly

Other warm-up tools whose bill grows with your mailboxes: MailReach, Warmup Inbox, Mailwarm and Warmbox

Like lemwarm, they mostly warm mailboxes that send from another tool (Warmup Inbox can also send sequences), and the price rises with the number of mailboxes, per address or by pack.

  1. 1

    MailReach

    Best for: A per-mailbox price that drops with volume, spam tests included

    $25 per mailbox a month from 1 to 5 mailboxes, then $19.50, $18 and $16 as you add more, on a quote above 100; $20 to $12.80 on yearly billing. Each mailbox gets up to 100 warm-up emails a day, and the plan includes at least 20 spam-test credits, one inbox placement test each. No trial shows on its pricing page.

    $16 to $25/month per mailbox
  2. 2

    Warmup Inbox

    Best for: A low price per mailbox, and a trial

    Basic costs $19 per mailbox a month ($15 on yearly billing) for 75 warm-up emails a day, with a lower average as you add mailboxes and a quote above 50. The 7-day trial needs no card, and the Basic plan includes an outreach-sequence module.

    $19/month for one mailbox
  3. 3

    Mailwarm

    Best for: A deliverability expert on call

    Plans come with a fixed number of mailboxes: Starter, $79 a month for one mailbox, Growth $189 for 3, each including calls with an expert. It asks for no IMAP access and offers no free trial. Its terms name COMUSE SAS, a company based in Rouen, France.

    From $79/month
  4. 4

    Warmbox

    Best for: Small fixed packs of mailboxes

    Warm-up sold in packs rather than per address: Solo for one mailbox, Start-up for 3, and a larger pack above that. One mailbox costs $15 or $19 a month depending on the billing period.

    $15 or $19/month for one mailbox

Warm-up with inbox placement tests: Warmy and Folderly

For when you want to know where your emails land, and why, more than to warm a mailbox. lemwarm on its own has no placement test.

  1. 1

    Warmy

    Best for: Warm-up priced by volume, with placement tests

    Warmy charges for the volume of warm-up emails you need rather than per mailbox, from $49 a month, and adds a deliverability tester with seed mailboxes, email verification and DMARC monitoring. It sends no campaigns; the 7-day trial needs no card.

    From $49/month
  2. 2

    Folderly

    Best for: A full deliverability service, on a yearly contract

    More a deliverability suite than a warm-up tool, with inbox placement tests (Inbox Insights) and monitoring. It is sold per mailbox and billed yearly only, at $96 a month per mailbox up to 9, $72 from 10 and $56 from 25, with a minimum commitment, after a demo rather than a trial.

    $56 to $96/month per mailbox, yearly

A free plan to start with: TrulyInbox

For a single mailbox and a tight budget.

  1. 1

    TrulyInbox

    Best for: Warming one mailbox for free

    The only one here that warms a mailbox for free: 1 account and 10 warm-up emails a day, without a card. Paid plans share a daily volume across as many mailboxes as you add, from $29 a month for 200 a day, with a 7-day trial and a refund within 14 days. It comes from the company that makes Saleshandy.

    Free, then from $29/month

lemwarm vs Warmup Inbox, Instantly and Warmy

Three pairings that come up in searches: another tool priced per mailbox, a sending tool, and a deliverability suite.

lemwarm vs Warmup Inbox

Both price warm-up per mailbox: $29 a month on lemwarm Essential against $19 on Warmup Inbox Basic, or $24 against $15 on yearly billing. Warmup Inbox states its daily volume (75 warm-up emails on Basic) and can be tried for 7 days without a card; lemwarm publishes no daily cap per plan and has no trial, but it comes free of extra charge with a paid lemlist plan.

lemwarm vs Instantly

Not the same kind of tool: lemwarm only warms, Instantly sends your cold email and warms every mailbox it connects. From 2 mailboxes, Instantly’s Growth plan ($47 a month) costs less than lemwarm alone, and it also sends, within 5,000 emails a month. lemwarm keeps the edge if you are happy with the tool that sends today and only need its mailbox warmed.

lemwarm vs Warmy

lemwarm bills each address; Warmy bills a volume of warm-up emails, from $49 a month, with placement tests that lemwarm on its own does not have. For one mailbox, lemwarm costs less than Warmy’s entry plan; Warmy makes more sense when the tests matter, or when one volume covers several mailboxes.

Choosing an alternative: five questions to settle first

Our email warm-up tools comparison sets these tools and a few others side by side, on price per mailbox.

  • Do these mailboxes also send your campaigns? Then a sending tool that includes warm-up spares you a second subscription.
  • How many mailboxes? A price per address only pays off for a single mailbox: from 2, Emelia’s plan costs less than lemwarm Essential (every case on the pricing page).
  • Do you need placement tests? MailReach, Warmy and Folderly include them; lemwarm leaves them to lemlist.
  • Who else is in the warm-up network? A network is only as good as the senders in it: look at who can join and what limits apply.
  • Can you try it first? Without a card: Warmup Inbox 7 days, Warmy 7, TrulyInbox 7, Instantly 14 and Emelia 7. lemwarm, MailReach, Mailwarm and Warmbox show no trial, and Folderly starts with a demo.

lemwarm alternatives: questions

It depends on the sending. To warm up and send in one tool: Emelia (with LinkedIn), lemlist (which already includes lemwarm) or Instantly. To keep warm-up apart from your sending tool: MailReach, Warmup Inbox, Warmy or TrulyInbox.

TrulyInbox, with a free plan for 1 account. Emelia, for its part, has no free plan: you test it for 7 days, no card asked.

Rather its natural home: every paid lemlist plan includes lemwarm Essential. If you would send from lemlist anyway, the separate lemwarm subscription goes away.

MailReach (spam-test credits in its plan), Warmy (deliverability tester) and Folderly (Inbox Insights); lemlist runs placement tests in its Deliverability Hub, paid in credits, and Instantly sells them as a separate subscription.

Emelia is our product, so take its place here with that in mind. It is listed for one need: warming mailboxes and sending the campaigns from the same plan, LinkedIn included.
