TheBoomerang Google mailboxes are good enough if you want low-cost Google Workspace-style inboxes and you don't mind a managed-service workflow. I used 30 mailboxes for 3 months, paid $2.50 per mailbox, and deliverability was not the issue that made me question the product.
The issue was operations.
Every time I needed changes, forwarding updates, or small mailbox-side fixes, I had to go back to their team. Setup usually took a day or two in my use, even though the public positioning talks about faster provisioning. That is fine if you are buying mailboxes once and leaving them alone. It is annoying if you run outbound like an operator and need to change things quickly.
Compared with Primeforge Google mailboxes, TheBoomerang wins on price. Primeforge wins on control, speed, and day-to-day infrastructure management. If deliverability is your only concern, TheBoomerang can work. If deliverability plus fast operational control matters, Primeforge is the cleaner choice.
Table of Contents
TheBoomerang is not a bad mailbox provider. It gives you cheap Google mailboxes, and my core deliverability experience was acceptable.
But I would not call it the best setup for teams that change forwarding, sender profiles, domains, or mailbox routing often.
| Category | My Take |
|---|---|
| Best fit | Budget-conscious teams that want managed Google mailboxes |
| Price paid | $2.50 per mailbox per month |
| Mailboxes used | 30 |
| Time used | 3 months |
| Deliverability | Good enough when the rest of the outbound setup is clean |
| Biggest problem | Manual support dependency for changes and forwarding |
| Setup time in my use | Usually 1-2 days |
| Primeforge comparison | Primeforge is faster and more self-serve, but costs more |
The better question is not, "Does TheBoomerang work?"
The better question is, "Do you want a cheap managed mailbox vendor, or do you want a mailbox control layer you can operate yourself?"
That is where the decision changes.
TheBoomerang started as a lead scraping and data product, but its infrastructure page now positions it as a cold email infrastructure platform for setting up and managing outbound mailboxes.
For this review, I am only talking about the Google mailbox side.
The public offer is straightforward:
The homepage also shows Google Workspace pricing around $2 per mailbox per month, while the broader site banner says Google Admin Mailboxes range from $1.80 to $2.50 per inbox. My actual cost was $2.50 per mailbox.
At 30 mailboxes, that is $75/month.
That is cheap.
But cheap infrastructure can still be expensive if every operational change requires a support loop.
I judged TheBoomerang like an outbound operator, not like someone comparing landing-page checklists. A mailbox provider has to protect inbox placement, but it also has to let you move fast when domains, forwarding, sender profiles, or campaigns change.
TheBoomerang's biggest positive is that the mailboxes did not feel like fragile throwaway inboxes.
With normal cold email discipline, the setup was workable:
If you burn a mailbox by blasting bad lists, TheBoomerang will not save you. No provider will.
But when the outbound basics were clean, I did not see deliverability as the main reason to avoid TheBoomerang. The problem is that deliverability is not only about the mailbox you buy.
It is also about the operating loop around that mailbox.
If forwarding breaks, replies are routed poorly, sender profiles are wrong, DNS needs a tweak, or you need to move mailboxes into a new sequencer, the mailbox is only as useful as your ability to fix the issue quickly.
That is where TheBoomerang felt slower than I wanted.
TheBoomerang works more like a managed mailbox service than a true self-serve infrastructure layer.
That can be good if you do not want to touch anything technical.
It becomes frustrating when you are actively running outbound and need to make changes without waiting on another team.
The pattern looked like this:
That is manageable for one domain.
It becomes slow across 30 mailboxes.
The specific pain point was forwarding. Every time forwarding needed to be changed, it went through their team. That means you are not really operating the infrastructure yourself. You are requesting changes to your infrastructure.
For a small static campaign, that is acceptable.
For a live outbound system, it slows down iteration.
TheBoomerang's public page talks about quick setup and streamlined onboarding. In my actual use, setup usually took 1-2 days.
That is not terrible.
But it matters when you are trying to launch a campaign this week, replace weak mailboxes, or spin up a new domain set after placement starts slipping.
Cold email infrastructure has a simple timing problem:
If the first step takes 1-2 days and every follow-up change goes through support, the whole system moves at the vendor's speed.
That works until your campaign calendar is tighter than their support queue.
Primeforge is more expensive on the mailbox line item, but the product is built around self-serve infrastructure control.
Primeforge publicly positions Google Workspace and Microsoft 365 mailboxes as cold-outreach mailboxes configured automatically and ready in about 30 minutes. Its pricing page shows mailbox slots, automated DNS setup, inbox hosting and maintenance, API access, and a minimum of 10 slots.
The key difference is not that Primeforge uses magic mailboxes.
The key difference is that Primeforge is a control panel for mailbox operations.
Here is the practical comparison:
| Factor | TheBoomerang | Primeforge |
|---|---|---|
| Google mailboxes | Yes | Yes |
| My paid mailbox cost | $2.50/mailbox/month | Higher, commonly $3.50-$4.50/mailbox/month |
| Setup in my experience | 1-2 days | Minutes to about 30 minutes |
| Forwarding changes | Support-mediated | Dashboard-first workflow |
| Best fit | Budget mailbox setup with managed help | Faster mailbox operations and self-serve control |
| Main tradeoff | Cheap, but slower changes | Costs more, but reduces waiting |
If you only look at mailbox price, TheBoomerang looks better.
If you include operator time, Primeforge starts to make more sense.
TheBoomerang is useful when the job is simple: get affordable Google mailboxes, let someone else handle the technical setup, and run campaigns without constantly changing the infrastructure.
I would consider it for:
The price is the obvious advantage.
At $2.50 per mailbox, 30 mailboxes cost $75/month. A higher-priced provider can be better operationally and still lose the budget argument for a small team that just wants to run a controlled test.
This is the competitor-wins scenario for TheBoomerang: if your setup is stable, your volume is moderate, and you are optimizing for low mailbox cost, TheBoomerang can be the better buy than Primeforge.
TheBoomerang starts to break when mailbox operations become part of your weekly workflow.
That means:
Most outbound teams underestimate this.
They compare mailbox vendors by price and inbox placement claims. Then, two weeks later, they are waiting for a forwarding update before a campaign can go live.
That is not a deliverability problem.
That is an operating model problem.
Good Google mailboxes help, but they do not create pipeline by themselves.
Your mailbox provider gives you the base layer. You still need the rest of the system:
TheBoomerang covers more of the processing for you.
Primeforge gives you more direct control over the processing.
That is the core tradeoff.
Do not choose TheBoomerang if you expect your mailbox infrastructure to change every week.
You will feel the support dependency.
I would avoid it if:
TheBoomerang is not the wrong tool because the mailboxes are bad.
It is the wrong tool when the operating model does not match how your team works.
Primeforge is the better choice when mailbox operations need to be fast, repeatable, and owned by your team.
That means the extra mailbox cost can be justified when:
The downside is cost.
Primeforge is not the cheapest Google mailbox option. Its pricing page shows mailbox slots at $4.50/month on yearly billing in the calculator example, with 2 months free on annual mailbox billing and a minimum of 10 mailbox slots. That is meaningfully more than the $2.50/mailbox I paid with TheBoomerang.
But this is where cheap can be misleading.
If Primeforge saves you repeated support waits, setup delays, and forwarding back-and-forth, the extra dollar or two per mailbox is not the real decision. The real decision is whether you want control or a managed queue.
TheBoomerang is good if your definition of good is "cheap Google mailboxes with acceptable deliverability and managed setup."
It is not as good if your definition of good is "I can control my mailbox infrastructure without waiting on support."
After 30 mailboxes and 3 months, my view is simple:
So, is TheBoomerang actually good?
Yes, for budget-managed Google mailboxes.
No, if you want an infrastructure control layer you can operate in minutes.
If your outbound team is still small and every dollar matters, TheBoomerang can make sense. If you are scaling campaigns and your mailbox setup needs to move at the same speed as your pipeline experiments, Primeforge is the cleaner system to run.
If you are evaluating TheBoomerang, do not buy 100 mailboxes first.
Buy 10-30, then test the operating loop:
That test will tell you more than any landing page.
Cheap mailboxes are useful.
Cheap mailboxes that slow down every campaign change are not.
If you would rather own the control layer from day one, Primeforge gives you real Google Workspace and Microsoft 365 mailboxes with automated DNS, US IPs, and self-serve management ready in about 30 minutes. Pair it with Warmforge for warmup and Salesforge for sequencing when you are ready to turn mailbox infrastructure into pipeline.
