First, the why

Why teams look past TrulyInbox.

TrulyInbox’s flat, pay-per-volume pricing is a real strength if your per-inbox volume stays light, since that daily volume is shared across every account. These are the four things that most often have people weighing up something else.

The free tier is too small to matter

The free-forever plan warms one account at 10 emails a day, which is nowhere near enough to warm a real sending mailbox. To do anything serious you are on a paid plan, so the headline of free warmup does not go far.

"Unlimited accounts" has a catch

Paid plans connect unlimited accounts, but the billing unit is daily warmup volume, and that volume is shared across all of them. So the harder you warm each mailbox, the fewer accounts a plan can realistically carry.

The pool is mixed, not Google and Microsoft only

TrulyInbox warms across a network of around 10,000 mixed Gmail, Outlook and IMAP accounts. That breadth is lower signal when the prospects you actually email are on Workspace and Microsoft 365.

Warmup alone is not the whole fix

Reviewers, and TrulyInbox’s own content, are honest that warmup cannot undo broken authentication, a bad list or a damaged reputation. The independent review base is also thin, with much of the praise published by TrulyInbox or Saleshandy themselves.

The list

The best TrulyInbox alternatives, ranked.

HotHawk

from $97/moOur pick

Warmup on real Google and Microsoft inboxes, built into a full sending platform.

Where it wins. TrulyInbox is the warmup layer under Saleshandy. HotHawk is the whole workflow in one place, with warmup on every plan. The pool is real Google and Microsoft inboxes only, more than 50,000 of them, against TrulyInbox’s mixed network of around 10,000. Each mailbox warms to its own daily limit rather than sharing one volume across accounts, risky inboxes are quarantined and bouncing ones suspended on the spot, and the Master Inbox and ClientBox come in the same $97 a month, with a 7-day trial and no card.

The trade-off. The honest catch on a warmup page: HotHawk is a full sending platform, not a warmup engine you bolt under a sender you already run. If pure warmup across a stack of accounts is all you need, a flat-rate tool will cost you less, and you bring your own leads either way.

Warmbox

from $15/mo

Automation-first warmup with a lot of dials, across a wide spread of ESPs.

Where it wins. Where TrulyInbox keeps the controls fairly simple, Warmbox is built for tinkering: Growth, Flat, Random and fully custom warmup styles, auto-remove-from-spam, auto-reply and mark-as-favourite, across Google and Outlook plus Yahoo, iCloud, Zoho, SendGrid and SES. If you need to warm odd provider types, it reaches further than TrulyInbox does.

Where it falls short. It charges per inbox and per team member, with no clearly advertised free trial, so it works out pricier than TrulyInbox’s flat volume model at scale. The mixed pool is lower signal for Google and Microsoft prospects, and some users still report mail going to spam.

MailReach

from $25/inbox/mo

Real Google and Microsoft warmup with a mature inbox-placement tester.

Where it wins. Warms on a network of 30,000-plus mostly Google and Microsoft accounts, higher signal for B2B than TrulyInbox’s mixed pool, and adds a proper spam test to 30-plus seed inboxes with per-provider diagnostics. It carries a 4.7 on G2 from a real review base, where independent TrulyInbox reviews are thin.

Where it falls short. It is per inbox at around $25 a mailbox with no free trial, so the cost is linear and you pay before you test, the opposite of TrulyInbox’s flat-rate, free-to-start model. The spam-test credits run out and cost extra.

Warmup Inbox

from $15/inbox/mo

A low-cost standalone warmup tool with a real-account network and a trial.

Where it wins. Around $15 an inbox on annual billing makes it one of the cheapest ways to warm a single mailbox properly, with a 7-day free trial and no card. The network spans real Google and Microsoft accounts plus others, and the higher tiers add language and ESP-specific warmup.

Where it falls short. The disclosed network is smaller than rivals, the analytics are basic, and because it is priced per inbox, the cost climbs quickly past a couple of mailboxes, unlike TrulyInbox’s flat volume pricing.

Smartlead

from $39/mo

A full sender with warmup and unlimited mailboxes on every plan.

Where it wins. Warmup and inbox rotation come bundled with the sender at $39 a month, mailboxes are unlimited, and per-mailbox analytics surface a failing inbox fast. Like TrulyInbox, it avoids per-inbox warmup charges, but it gives you the sending platform too.

Where it falls short. It is a full sender, so moving to it is a workflow change rather than a warmup swap. White-label is a $29 per client add-on, and support and reliability are its most common complaints.

Maildoso

from Warmup add-on from $160/mo

Done-for-you domains and inboxes, with a separate AI warmup add-on.

Where it wins. Its real strength is supplying inboxes: domains and mailboxes from around $0.49 each, self-healing mailboxes and IP rotation, ready in minutes. If your gap is mailboxes to send from rather than warmup, it covers it.

Where it falls short. Its warmup runs on AI browser bots rather than real inboxes, where TrulyInbox uses real accounts, and it costs $160 to $2,000 a month on top of the mailboxes, covering only Gmail and Outlook with no Microsoft 365.

How we ranked these

Our method.

We ranked these on what matters for warmup that protects a domain: the make-up of the warmup pool, the providers it covers, how much real control you get per mailbox, and the true cost once you count volume and accounts. Pricing and features come from each tool’s own website as of June 2026, and the weak points come from public user reviews.

HotHawk is our own product, so we have put it first, and we have been straight that it is a full sending platform rather than standalone warmup, which makes it a bigger switch than swapping warmup engines. We have also credited TrulyInbox’s flat-rate economics where they genuinely beat us, and noted that it uses real accounts and AI content just as we do. No tool paid to be here, and there are no affiliate links.

FAQ

TrulyInbox alternatives, answered.

Is TrulyInbox the same as Saleshandy warmup?

Effectively, yes. TrulyInbox is the warmup engine behind Saleshandy: Saleshandy’s help docs provide warmup through its partner TrulyInbox, free on paid plans, on a pool of more than 10,000 accounts. So a TrulyInbox alternative is also a Saleshandy-warmup alternative. The tools below cover both standalone warmup and senders that include warmup of their own.

What is the best TrulyInbox alternative?

It depends on the job. If you want warmup built into the tool you send from, HotHawk and Smartlead include it on a per-account-free basis. If you want a more customisable standalone tool across many providers, Warmbox reaches further. If you want standalone warmup with a real spam tester, MailReach is the pick. The deeper question is often whether you need a separate warmup tool at all.

Why do people switch from TrulyInbox?

Usually because the free tier is too small to warm a real account, the mixed pool is lower signal than a Google and Microsoft-only one, or the shared-volume model limits how many accounts a plan really supports. The thin independent review base is the other common reason teams want a more proven option.

Is there a cheaper TrulyInbox alternative?

For light warmup on a budget, TrulyInbox’s flat pay-per-volume pricing is hard to beat on sticker price, though its daily volume is shared across every account, so it does not actually scale to warming a lot of inboxes hard. Where the alternatives pull ahead is bundling: HotHawk and Smartlead fold warmup into the sender, so you are not paying for warmup as a separate line at all, which often works out better value once you count the sender you would otherwise buy.

Do I actually need a standalone warmup tool?

Often not. If your sending platform already warms your mailboxes, like HotHawk does on a pool of real Google and Microsoft inboxes, a separate warmup subscription is just another login and another bill. A standalone tool like TrulyInbox makes sense mainly when you want to warm inboxes you send from somewhere that has no warmup of its own.
