Emelia: keep warming and sequencing, add LinkedIn and email finding
- 1
Best for: Warm-up, sequences and LinkedIn on one billLike Warmup Inbox, Emelia warms each mailbox it connects and sends cold email sequences from it, so a move keeps both jobs in one tool. The bill is built differently: a plan covers a set of mailboxes (3 on Start for $37 a month, 50 on Grow for $97) instead of a rate per inbox, and it adds LinkedIn accounts, email and phone finding in credits that stay valid for a year, and a CRM integration. What Emelia lacks is a placement test on seed inboxes, which Warmup Inbox offers for free.

- Who it’s for
- Teams that send from several mailboxes and want LinkedIn steps and contact finding on the same subscription.
Warming a single inbox
For one address, Warmup Inbox Basic costs $19 a month, or $15 paid yearly. These three are priced for that case too: a free tier, a one-mailbox plan, or a rate per mailbox.
- 1
Best for: One account at no costTrulyInbox prices a daily warm-up volume shared by all your accounts instead of charging per inbox, and it keeps a free tier for 1 account. Its paid plans begin with Starter at $29 a month ($22 yearly), which it suggests for about 3 accounts, with a 7-day trial and no card. It only warms: campaigns stay in your sending tool, whereas Warmup Inbox can send them itself.

Best for: A one-mailbox planWarmbox’s Solo plan covers 1 mailbox for $19 a month, or $15 on yearly billing, the very figures of Warmup Inbox Basic for one inbox. The paths split as you grow: Warmbox sells plans with a set number of mailboxes (3 on Start-up at $79, 6 on Growth at $159), where Warmup Inbox lowers its rate inbox by inbox. Warmbox sends no campaigns.

Best for: Warm-up with spam tests in the planMailReach also charges per mailbox, $25 a month up to 5 and less in the larger tiers, and its plan comes with 20 spam-test credits a month, each one a placement test with its report. It concentrates on deliverability and leaves the sending to the tool you already use, whereas Warmup Inbox can run sequences itself.

3 to 10 inboxes
Between 3 and 10 inboxes, Warmup Inbox Basic comes to $54.45 a month for 3 and $160 for 10. Here the alternatives part ways on how they count: one daily volume for all inboxes, a flat rate per address, or plans for a fixed number of mailboxes.
- 1
Best for: One daily volume for any number of inboxesMailivery sells a daily warm-up volume rather than inboxes: Starter, at $29 a month ($21.75 yearly), spreads it over as many inboxes as you connect, with a cap per inbox and 10 placement test credits included. With 3 inboxes, that plan costs less than Warmup Inbox’s $54.45, and each inbox you add draws on the same daily allowance. It sends no campaigns; its 7-day trial starts on Starter.

Best for: A flat price per addresslemwarm charges $29 a month per address on Essential ($24 yearly), whatever the number of addresses, with volume pricing only on a Custom quote above 10 users; 3 addresses cost $87 where Warmup Inbox’s slider gives $54.45. It has no trial of its own and, bought alone, sends no campaigns; inside a paid lemlist plan, it comes at no extra charge.

Best for: Plans with calls from a deliverability expertMailwarm sells plans for a fixed number of mailboxes, each with calls with a deliverability expert: Starter at $79 a month for 1, Growth at $189 for 3, Scale at $549 for 10. That is well above Warmup Inbox’s rate for the same inboxes, for a service built around those calls. There is no classic free trial and no campaign sending.

50 inboxes and more: sending platforms and deliverability services
At 50 inboxes, Warmup Inbox Basic reaches $475 a month, and above that it works out a quote. Sending platforms include the warm-up of the inboxes they connect; deliverability services sell it on its own, with more testing or more support.
- 1
Best for: Unlimited inboxes warmed on one sending planInstantly’s Growth plan, $47 a month ($37.60 yearly), connects unlimited inboxes and warms every one, with 5,000 emails a month to send. At 50 inboxes, the price stays the same, where Warmup Inbox’s grows with every inbox; Instantly also sells a B2B lead database and a CRM. Neither tool runs LinkedIn steps.

Best for: A sending plan priced by volume, warm-up includedSmartlead’s Base plan, $39 a month, includes warm-up for the inboxes you connect and covers 6,000 emails a month to 2,000 contacts. Like Warmup Inbox, it sends from your own inboxes; unlike it, the price follows the sending volume rather than the number of inboxes. LinkedIn is not built in: it goes through third-party tools such as HeyReach.

Best for: lemwarm included in a sending planlemlist’s Email plan, $69 a month for up to 50,000 emails, includes lemwarm Essential for the addresses you connect, at no extra charge. At 50 inboxes, the warm-up then sits inside the sending bill rather than at a rate per inbox, as on Warmup Inbox. lemlist also has a B2B contact database and multichannel plans with LinkedIn steps, priced higher.

Warmup Inbox compared: Instantly, lemwarm, Warmy, MailReach, Folderly
The bill stops following the inbox count: Instantly Growth costs $47 a month whether you connect 3 inboxes or 50, warm-up included, while Warmup Inbox Basic goes from $54.45 to $475 over that range. You keep sending from your own inboxes and can add a lead database and a CRM, each a separate Instantly subscription (from $9 and $47 a month). Neither runs LinkedIn steps, which Emelia adds in the same plan as the warm-up.
lemwarm charges $29 per address each month on Essential, with no published volume discount (only a Custom quote above 10 users) and no trial; Warmup Inbox starts at $19 and lowers its average as inboxes are added. Bought alone, lemwarm sends no campaigns, while Warmup Inbox plans include sequences; lemwarm is also included at no extra cost in a paid lemlist plan.
For 3 inboxes billed monthly, Warmup Inbox Basic comes to $54.45, MailReach to $75 and Warmy Starter to $147. MailReach adds spam-test credits, Warmy placement tests in every plan, and Warmup Inbox sequences sent from those inboxes. Emelia Start connects the same 3 mailboxes for $37, with sending and a LinkedIn account.
Folderly is a different purchase: per-mailbox plans billed only by the year, with a minimum commitment, and placement tests through its Inbox Insights product. Its entry rate is $96 a month per mailbox, billed by the year, and it sends no campaigns, where Warmup Inbox plans include sequences. Folderly’s yearly fee pays for a managed service built around those tests.
