Warmup Inbox Pricing: Per Inbox, Annual Loads First

Warmup Inbox prices per inbox, and its pricing page loads on the annual state. The Monthly and Annual switch above the ladder opens with Annual selected and a Save 20% badge, so the first figures a visitor sees are the discounted ones. As published on Warmup Inbox's pricing page on 2026-09-04, those are Basic at $15 per inbox a month, Pro at $49 and Max at $79, each with the annual total printed underneath: $180, $588 and $948 billed yearly. Switch to Monthly and the same plans read $19, $59 and $99 per inbox a month, billed monthly.

The per-inbox meter means the plan you choose is a rate, and your bill is that rate times the inboxes you connect. The page prices the rate; the count is yours.

The ladder at both states

BasicPer inbox

• Seventy-five warmup messages a day
• The lowest reply ceiling of the three
• The entry rate for a small fleet

ProPer inbox

• Two hundred and fifty warmup messages a day
• A higher reply ceiling than Basic
• The middle tier for active senders

MaxPer inbox

• One thousand warmup messages a day
• The highest reply ceiling on the ladder
• For mailboxes that send at volume

Basic. On the page, $15 per inbox a month billed yearly, $180 a year per inbox, or $19 per inbox a month billed monthly. 75 warmup messages a day, reply rate up to 25%.

Pro. On the page, $49 yearly, $588 a year, or $59 monthly. 250 warmup messages a day, reply rate up to 45%.

Max. On the page, $79 yearly, $948 a year, or $99 monthly. 1,000 warmup messages a day, reply rate up to 50%.

Agencies. Custom pricing from 15 inboxes, with the page stating larger discounts past 50.

The annual saving is close to the 20% the badge states on Basic ($19 to $15 is 21%) and smaller on the upper tiers ($59 to $49 is 17%, $99 to $79 is 20%). The page also states that annual plans are billed once for twelve months.

The meter is per inbox, and the volume is per inbox too

Unlike a plan-pooled warmup product, every Warmup Inbox limit is per inbox. A Basic inbox warms at up to 75 a day and a Max inbox at up to 1,000 a day, and a fleet can mix them. The price scales with the count, so ten Basic inboxes billed yearly is $150 a month and ten Max inboxes is $790 a month.

1. Step 1Choose a plan per inbox

   Each connected inbox carries its own plan and its own daily volume cap.

2. Step 2Multiply by inboxes

   The bill is the per-inbox rate times the inbox count at the chosen billing state.

3. Step 3Add mid-month

   The FAQ states that an inbox added partway through a period is prorated.

4. Step 4Past fifteen inboxes

   Agency pricing takes over, with larger discounts past fifty.

The reply rate ceiling is the second meter and the one buyers tend to skip. A warmup network sends messages to your inbox and replies to yours; a higher reply ceiling means a higher share of your warmup sends get answered, which is what the mailbox providers appear to weight. Basic caps replies at 25% of sends, Pro at 45%, Max at 50%. For a mailbox that only needs 50 warmup messages a day, the argument for Pro over Basic is the reply ceiling rather than the volume.

Trial and proration

The FAQ states a seven day free trial with no card required, and that an inbox added mid-month is prorated so you pay only for the remaining days. Those two terms together make the product cheap to test: connect one inbox, watch it for a week, add the fleet when you are ready and pay from that day.

Who the vendor says it is for

The customers page names Mangools, Wishpond, SellersCommerce, Leadspicker, i-batu and Avvy, a mix of SaaS, ecommerce and sales automation firms, and the site's by-role menu names sales, marketing, agencies and recruiters. The agency tier from 15 inboxes is sized for a firm warming client fleets rather than its own.

Pricing a real fleet

A team with eight sending mailboxes on Basic pays $120 a month billed yearly, $1,440 a year, or $152 a month monthly. Move the same eight to Pro for the higher reply ceiling and it is $392 a month yearly or $472 monthly. That step, from $15 to $49 per inbox, is the largest on the ladder in proportional terms, more than tripling the rate, and the volume goes from 75 to 250 a day. A fleet that does not need the volume is paying for the reply ceiling alone.

At the top, Max at $79 per inbox yearly with 1,000 messages a day is priced for a mailbox that sends at real volume. A cold email mailbox sending 30 to 50 campaign emails a day is warmed by a Basic inbox at 75 warmup messages a day at one and a half to two and a half times its campaign volume. Max is for a different kind of mailbox.

Set against MailReach, the other per-inbox product read the same day, whose bands run from $25 down to $16 a mailbox monthly as published on its own page, Basic at $15 yearly sits under MailReach's lowest band and Pro at $49 sits above its highest; the warmup services survey prices the rest of the category. The vendor's nearest alternatives are mostly single-rate per-inbox products, so the comparison is Basic against their rate for a low-volume mailbox and Pro or Max for a high-volume one.

Mixing plans across a fleet

Because each inbox carries its own plan, a fleet does not have to be uniform. A sensible shape is a small number of high-volume mailboxes on Pro or Max and the rest on Basic. A team with twelve mailboxes, two of which send at real volume, could run two on Pro and ten on Basic for $248 a month billed yearly, against $588 for all twelve on Pro. The page does not describe any limit on mixing, and the agency threshold of 15 inboxes counts inboxes rather than plans.

The reply ceiling makes the choice per mailbox rather than per team. A new domain in its first month wants the higher ceiling, because replies are the signal that a fresh sender is legitimate; an established mailbox that has been sending for a year wants volume maintenance more than replies. Moving a mailbox from Pro to Basic after its ramp is a change the per-inbox meter allows and a plan-pooled meter would not.

What the rate buys against running warmup yourself

The alternative to any warmup product is warming by hand: sending real mail at low volume for weeks and rising slowly. That costs nothing in subscription and several weeks in time, and it produces fewer replies than a network does. At Basic's $15 a month yearly, the product costs $45 for a three-month ramp per inbox, which is a small number against the campaign volume a mailbox sends once warm. The case against paying it is a sender or mailbox vendor that already bundles warmup, in which case the product duplicates something you have.

The trial runs on one inbox at a time, per the FAQ's description, so a team testing the network should pick the inbox that most needs the help rather than the healthiest one.

Reading the third-party numbers

Roundups quote this vendor at $15 and at $19, and some quote Pro at $59 and Max at $99 without a billing state. All of those figures are on the page today; the first set is the annual tab the page opens on, the second is the monthly tab. One roundup also states a half-yearly billing option with a 10% saving, which the page does not print, so it is not in this article.

Warmup is a cost of sending, priced separately

Warmup Inbox is a warmup product only. It does not send campaigns. If your sender bundles warmup, this is a line you may not need; if your mailbox vendor does not, it is a line you will pay somewhere, and the mailbox pricing guide sets out why warmup should be priced as its own item whether it is bought, run in another tool, or absorbed as slow ramping. The warmup tools review covers how these products behave once connected, and the deliverability guide covers what warmup can and cannot fix.

What it cannot fix is sending discipline. A warmed inbox that sends the same offer twice to the same list, or that chases the people who did not reply with a LinkedIn message carrying the same pitch, is spending the reputation the warmup built. One message per campaign, sent once, costs nothing and does more than any reply ceiling.
