lemwarm alternatives: warmup inside the mailbox, priced at 2,500 emails a day
lemwarm warms one email address per subscription, $29 a month on Essential and $49 on Smart, and it comes free with every lemlist plan. It sells no mailboxes, domains or sequencer, so outside lemlist it is a fourth bill next to the mailboxes, the domains and the sending tool. At 2,500 cold emails a day lemwarm for 63 addresses and an Instantly plan come to at least $1,924 a month before a single mailbox. 100 Outreach2day mailboxes send the same with warmup and our sequencer for $171.67. We make Outreach2day and list it first.

Compared at the same emails a day, each vendor at its own published emails per mailbox a day: a cheap mailbox that sends 5 a day costs more per email than one that sends 25. Every option at 2,500 a day · 55,000 a month (22 sending days). lemwarm and its alternatives at the same mailbox count. Mailboxes = emails a day ÷ each vendor's emails per mailbox a day; monthly list prices on monthly billing, with the cheapest plan of the sequencer named in each row that covers the volume (Instantly unless the vendor's mailboxes need another; both include warmup). Domains at each vendor's published price spread over 12 months; "from" means a domain price is not published. A mailbox-only vendor cannot send campaigns on its own, so its total is the full sending setup: its mailboxes, domains and the sequencer plan that covers the volume. Instantly is the reference sequencer, on its published plans for the emails and new contacts a month (emails ÷ 3); Smartlead where Instantly publishes no plan; Mailforge with Salesforge, because its mailboxes cannot be warmed in Instantly. The mailbox line is listed on its own in every cell.

Outreach2day: 25 cold emails per mailbox a day, 5 mailboxes per domain, .com domains at $13 a year (1,000 mailboxes and 200 domains at 25,000 a day; 40,000 and 8,000 at 1,000,000). Instantly and Smartlead with the accounts they sell, at the published plan for the volume; mailbox vendors at their own emails-per-mailbox limit with their domains and the Instantly (Mailforge: Salesforge) plan for the volume. A month is 22 sending days, so emails a month = emails a day × 22. Where a vendor publishes no price at that size the cell says so and the chart leaves it out. At this size the main table's flat $2.50 a Maildoso mailbox gives way to its published packs.

Every option is priced for the same 2,500 cold emails a day, each at its own emails per mailbox a day, with Instantly for sending where the vendor has no sequencer. lemwarm's help center sizes a mailbox at 30 to 40 emails a day in lemlist; at 40 the row warms 63 addresses at $29, $1,827, plus Instantly Hypergrowth at $97: $1,924 before the mailboxes, which Instantly already warms in every plan.
Outreach2day is $171.67 with warmup, the sequencer and 20 domains. InboxKit with Instantly starts at $286 before domains, InfraBoxes at $397, Zapmail is $432.83, TrulyInbox's suggested plan with Instantly from $576 and MailReach from $673, both before the mailboxes.

We move your mailboxes and campaigns for you, free
Switching
Moving from lemwarm to Outreach2day
Keep your sequencer
Connect Instantly or Smartlead in Outreach2day with an API key and the warm mailboxes are added to your account; other tools take a CSV in their import format, or SMTP/IMAP logins. How the export works
Or move the campaigns
Our sequencer runs campaigns with steps, a send schedule, stop on reply and one inbox for replies; import the contacts as a CSV and recreate the steps. The mailbox price stays $2.50.
Warmup and the overlap
New mailboxes warm for 14 days before cold email, and warmup keeps running after that. Keep the lemwarm mailboxes sending during those two weeks, then shift the volume and cancel lemwarm for the end of its billing period.
lemwarm does not refund unused time in a started month or year. Remove addresses from lemwarm at the end of a billing period, once warmup runs in your sequencer or at your new mailbox provider; inside lemlist the warmup stays included.

Choosing
Why lemwarm users look for an alternative
Cost per address is the first reason. $29 a month to warm one address is more than ten Outreach2day mailboxes at $2.50 with warmup included, and at $0.50 from 1,000 the gap is larger. Teams that send from Instantly or Smartlead already pay for warmup in the plan.
The second is the ramp. lemwarm's beginner guide adds one warmup email a day for about 40 days and then holds 14 more before the first campaign. Outreach2day mailboxes warm for 14 days and send up to 25 cold emails a day from day 14, with warmup still running.
lemwarm inside lemlist
If you send from lemlist, lemwarm costs nothing extra: Email Pro warms up to 3 addresses and Multichannel Expert up to 5. The comparison changes when the mailboxes outnumber those slots or when you send from another tool. The full lemlist bill is in lemlist pricing, and the sequencers that replace it are in lemlist alternatives.
Our email warmup service post explains what our warmup does, and the best warmup tools post compares lemwarm with the other standalone tools.
