Every article about email warmup assumes you need it. Before you spend anything on Warmup Inbox, here is the question that decides it: is the address you are emailing suppliers from brand new, or has it been sending normal business mail for a year or more?
If it has history, my view is that warmup is solving a problem you do not have. If your domain was registered last month and you are about to email forty manufacturers from it, that is exactly the situation warmup exists for.
The second thing worth knowing before you look at the pricing page is the unit. The plans are priced per inbox, not per account, and each listed plan includes one inbox. Almost every article about this product quotes the headline figure as if it were your whole bill.
Every price, limit and quoted phrase below comes from Warmup Inbox’s own pricing page, plus Google’s published sender guidelines and the FTC’s CAN-SPAM guide, all read on 29 September 2026. Where a figure is my own arithmetic or my opinion, I say so, and I am not a lawyer.
I run Ecommerce Paradise. If the model is new to you, start with what high-ticket dropshipping actually is.
Seven Days, No Card
Warmup Inbox advertises a “7-day free trial” on all three plans, with “No credit card required” and “Cancel anytime during the trial – you won’t be charged.”
The Pricing, With the Unit Made Obvious
Warmup Inbox’s pricing page lists three self-serve plans plus an enterprise option.
| Plan | Price | Annual | Inboxes included | Daily warmup limit |
|---|---|---|---|---|
| Basic | “$15/inbox/mo” | $180 | 1 | “75 warmup messages/day” |
| Pro | “$49/inbox/mo” | $588 | 1 | “250 warmup messages/day” |
| Max | “$79/inbox/mo” | $948 | 1 | “1,000 warmup messages/day” |
| Enterprise | Custom, 51 or more inboxes | Custom | 51+ | Not stated |
Read the price column again. It is per inbox per month, and each plan includes one inbox. If you are warming three sending addresses on Basic, that is three times $15, which is $45 a month by my own multiplication, not $15.
The annual figures are worth checking too. By my own arithmetic, $15 times twelve is $180, $49 times twelve is $588, and $79 times twelve is $948, which are exactly the annual figures listed. So the page shows no annual discount at all, on any plan. That is unusual and it means there is no cash-flow reason to commit for a year.
The enterprise tier is described as being for 51 or more inboxes, with the page saying “we need to know more about your setup to adjust to your needs”. If you are reading a setup guide for a store, that is not you.
I have covered the plans further in my Warmup Inbox pricing guide.
Which Plan, and Why It Is Almost Certainly Basic
The only thing that changes between the three plans is the daily warmup message limit: 75 on Basic, 250 on Pro, 1,000 on Max.
Now think about what that limit is for. Warmup volume should bear some relationship to your real sending volume, because the point is to build a normal-looking sending pattern. A store owner emailing forty suppliers over three weeks is sending perhaps three or four real emails a day.
Against that, 75 warmup messages a day is already generous. Two hundred and fifty is for somebody running cold outreach at scale, and a thousand is for an agency with many domains in flight.
So my conclusion, and it is mine rather than the vendor’s: Basic, at $15 per inbox per month, is the plan for a high-ticket store. If you find yourself wanting Max, the honest question is not which warmup plan to buy but whether you have accidentally become a cold-email business rather than a retailer.
What Warmup Actually Does
Worth describing mechanically rather than in marketing terms, because the marketing in this category makes claims I cannot check.
A warmup service connects to your mailbox and exchanges messages with other mailboxes in its network, sending and replying across it. The vendor describes that as building a record of normal correspondence for your address. I have not verified what happens beyond the sending and replying, so I will not describe more of the mechanism than that.
What I am not going to tell you is by how much that helps, or that it is required, because nothing I read establishes either. Vendors in this category publish confident numbers about deliverability improvements and I have no way to verify any of them.
What I will say is that the underlying logic is sound: a brand new address that suddenly sends forty messages to strangers looks different from one with months of ordinary two-way correspondence behind it. Whether a warmup service is the best way to build that history, or whether simply using the address normally for a few weeks does the same job, is a judgement call, and I would not pretend it has an obvious answer.
Or Have the Outreach Done
My done-for-you builds include the supplier sourcing and the dealer approvals, so the outreach and the follow-up are handled rather than learned.
Step 1: Decide Whether You Need This At All
The honest first step, and the one that may end the article for you.
You probably do need warmup if: the domain was registered within the last few months, the mailbox is new, you have never sent from it, and you are about to send a batch of messages to people who have never heard from you.
You probably do not need it if: you have been running the business from that address for a year, you correspond with customers daily, and you are adding forty supplier emails to an established pattern of normal sending.
The middle case, a domain with some history but a new mailbox on it, is genuinely ambiguous and the 7-day free trial is a cheap way to settle it. Use it rather than guessing.
Step 2: Fix Authentication First
Warmup on an unauthenticated domain is building a reputation for something receiving servers cannot properly identify. Do this before you start, not after.
Google’s email sender guidelines tell bulk senders to “Set up SPF and DKIM email authentication for your domain” and to “Set up DMARC email authentication for your sending domain.” Google’s threshold for a bulk sender is stated as: “Starting February 1, 2024, email senders who send more than 5,000 messages per day to Gmail accounts must meet the requirements in this section.”
Your supplier outreach is nowhere near 5,000 messages a day, so those requirements are not formally aimed at you. But my view is that SPF, DKIM and DMARC are worth setting up at any volume, because authentication is what lets a receiving server tell that your mail is genuinely from your domain.
Google also publishes spam-rate guidance for bulk senders: “Keep spam rates reported in Postmaster Tools below 0.30%”, with a recommendation to keep them “below 0.10%”. I mention those as reference points rather than as thresholds applying to you at a store’s volume.
Step 3: Verify the List Before the First Real Send
Warmup builds a sending record. Bouncing off invalid addresses is the obvious thing working against it.
Supplier addresses are frequently guesses, worked out from a contact page or a name format, and a warmed inbox that then bounces off a dozen wrong guesses is working against the record you have just been building. That is my reasoning rather than a measured effect, but verifying first costs nothing at this list size.
I wrote up how I verify a supplier list separately, and on a list of a few dozen addresses EmailListVerify’s free verifications on signup cover the whole job. The ZeroBounce setup guide covers the same job on the other major service if you would rather use that one.
Step 4: Run Warmup Alongside Real Sending, Not Instead of It
A mistake I see often: people warm an inbox for a month while sending nothing real, then send forty cold emails on day thirty-one.
That is a strange pattern from a receiving server’s point of view. The more sensible shape, in my view, is to let warmup run while you also send genuine correspondence from the same address, and to start your supplier outreach gradually rather than as a single batch.
Five supplier emails on Monday, five on Wednesday, and so on, is both better for your sending pattern and better for you, because you can actually read and act on the replies instead of drowning in them.
Step 5: Keep the Messages Themselves Legal
Warmup does nothing about content, and content is where the rules live.
The FTC’s CAN-SPAM compliance guide sets out eight main requirements for commercial email under US law. In summary: no false or misleading header information; no deceptive subject lines; identify the message as an ad; include your valid physical postal address; explain clearly how to opt out; remember that subscribers and members can opt out too; honor an opt-out request within 10 business days; and monitor what others do on your behalf. The guide states a maximum civil penalty of up to $53,088 per violation, as read on the date above.
That is a summary of a government guide rather than legal advice. Google separately requires that “Marketing messages and subscribed messages must support one-click unsubscribe, and include a clearly visible unsubscribe link in the message body”, and does not state a processing timeframe for those, so do not assume the FTC’s 10-business-day figure carries across.
The valid postal address requirement is one more reason to have the business properly set up, which is covered in business formation for high-ticket dropshipping.
Step 6: Decide When to Stop Paying
Almost nobody writes this part, and it is the part that saves you money.
Warmup is a fix for a new address with no history. Once the address has months of genuine two-way correspondence with real suppliers and customers behind it, the thing warmup was simulating is now actually happening, and my view is that the subscription has done its job.
By my own arithmetic on the figures above, the page shows annual pricing at exactly twelve times the monthly rate, so I saw no discount for committing. I did not read anything about the billing terms themselves, so check those before you commit, but on price alone there is no reason to pay for a year up front.
I would not run warmup permanently on a single established business address. That is my opinion, and the vendor would presumably disagree, so weigh it accordingly.
What This Costs Over a Year
| Setup | Cost |
|---|---|
| 7-day trial, no card required | $0 |
| Basic, one inbox | $15 a month, listed at $180 annually |
| Basic, three inboxes | $45 a month by my own multiplication |
| Pro, one inbox | $49 a month, listed at $588 annually |
| Max, one inbox | $79 a month, listed at $948 annually |
The three-inbox figure is my own multiplication of the published per-inbox price. The annual figures are the ones the page lists, and by my own arithmetic each is exactly twelve times the monthly rate, so I found no annual saving.
For a high-ticket store the honest version of that table is the second row, for a few months, and then nothing.
Where This Sits in the Rest of the Build
Warmup is plumbing for a sending address. It does not find suppliers, write your approach email, or make a manufacturer reply to you.
The sourcing is the hard part, and my guide to finding high-ticket suppliers covers the whole process. If the niche is not settled yet, start with my high-ticket niches list instead, because none of this matters until it is.
Once suppliers reply, the conversation needs somewhere to live, and I wrote up how I set up a CRM for quote requests for that side of it.
The Whole Thing, in Order
| Step | What you do |
|---|---|
| 1 | Ask whether your sending address is actually new, and skip this if it is not |
| 2 | Use the 7-day trial rather than guessing, since no card is required |
| 3 | Choose Basic, because 75 warmup messages a day suits a store’s real volume |
| 4 | Remember the price is per inbox, and multiply by how many you are warming |
| 5 | Set up SPF, DKIM and DMARC before warmup starts, not after |
| 6 | Verify your supplier list so warmup is not undone by bounces |
| 7 | Send genuine correspondence from the address while warmup runs |
| 8 | Start outreach gradually, a handful at a time, rather than in one batch |
| 9 | Put a valid postal address and a clear opt-out in every message |
| 10 | Cancel once the address has real history, since paying annually buys no discount |
Step 1 is the one that may save you the whole subscription, which is why it comes first.
Warm a New Sending Address
Basic is listed at “$15/inbox/mo” with “75 warmup messages/day”, and every plan comes with a 7-day free trial and no credit card required.
Six Mistakes to Avoid
Buying it for an established address. Warmup is for new addresses with no sending history, in my view.
Reading the price as per account. It is per inbox per month, and each plan includes one inbox.
Buying Pro or Max for a store. The only difference is the daily limit, and 75 a day already exceeds a store’s real sending volume.
Warming before authentication. SPF, DKIM and DMARC come first, in my view, or you are building reputation for something unidentifiable.
Sending an unverified list afterwards. Bounces work against the sending record warmup is building, in my view.
Paying forever. There is no annual discount on the page, so there is no price reason to commit beyond the months you actually need it.
Frequently Asked Questions
What does Warmup Inbox cost?
Basic is listed at “$15/inbox/mo”, Pro at “$49/inbox/mo” and Max at “$79/inbox/mo”, with annual figures of $180, $588 and $948. Enterprise is custom for 51 or more inboxes.
Is the price per account or per inbox?
Per inbox per month. Each listed plan includes one inbox, so warming three addresses on Basic costs three times $15 by my own multiplication.
Is there an annual discount?
By my own arithmetic the listed annual figures are exactly twelve times the monthly rates, so I found no annual saving on the page.
What is the difference between the plans?
The daily warmup message limit: “75 warmup messages/day” on Basic, “250 warmup messages/day” on Pro, and “1,000 warmup messages/day” on Max.
Is there a free trial?
All three plans list a “7-day free trial” with “No credit card required” and “Cancel anytime during the trial – you won’t be charged.”
Do I actually need warmup?
In my view only if the sending address is genuinely new. An address with a year of normal business correspondence behind it already has what warmup is trying to build.
Does warmup improve deliverability?
I am not going to give you a figure, because nothing I read establishes one. What it does mechanically is exchange messages with a network of mailboxes to build a sending and receiving record.
How long should I run it?
My view is until the address has genuine two-way correspondence behind it, then cancel. I saw no annual discount on the page, so committing for a year buys you nothing on price.
Which plan for a high-ticket store?
Basic. A store emailing suppliers sends a handful of real messages a day, and 75 warmup messages against that is already generous.
Should I still verify my list?
Yes, in my view. Warmup builds a sending record and bounces work against it, so verification and warmup are complementary rather than alternatives.
