Testimonials

Verified client reviews:

"As a dev, I hate dealing with SMTP servers and warming up domains. InboxRev took the entire infrastructure burden off my plate. Our deliverability has never been higher, and I can finally focus on coding instead of fighting spam filters." — Tirsin Nicholas, Verified Founder
"I've really enjoyed working with this team. They're responsive, professional, and easy to work with. What I appreciate most is that they actually take the time to understand my business and make adjustments as we go, instead of treating it like a cookie-cutter service." — Abdul Karmach, Verified Client
"If you run outbound and you're trying to get cold email right, Patrick at InboxRev is who you want in your corner. He helped me fix my email and delivery frameworks, fixed gaps in my copy, and was always keen to give me feedback to improve conversions." — Mason Gervasio, Verified Outbound Lead
"My experience with Inboxrev has been great overall. Patrick and team are highly knowledgeable and experienced in outreach and capturing high quality sales conversations and bookings. They do what they say which is rare in this industry. I highly recommend them." — Kimberly, Verified Executive

"I paid Patrick for calls booked and he really helped with email marketing in my space which is B2B Software. High caliber team, outstanding responsiveness, and rock-solid deliverability infrastructure." — Alex Johnson, B2B Software CEO

Frequently Asked Questions

How fast do intros start landing?

7 to 10 days from kickoff to live sending. First qualified replies typically land in week 2, first warm intros in weeks 2 to 3, and a steady weekly cadence by week 4. We run the 14-day domain warm-up in parallel with list building and copy, so no time gets wasted.

What does it cost?

$6,000 per month, flat. Everything is included: data sourcing across dozens of databases, sequencer, inboxes, isolated sending domains, reply handling, and warm intro coordination. No extra tool licensing to stack on top.

Is there a contract?

Month-to-month. No lock-in, no minimum term, no cancellation fee. If we are not delivering, you leave. Every InboxRev client is on month-to-month because we would rather re-earn you every 30 days than trap you for a year. That said, we strongly recommend testing over a full quarter (90 days) so the system has time to compound and you can see steady pipeline.

Do I own the infrastructure?

Yes. Every domain, inbox, list, and reply thread is yours. If you leave, we hand over the domains, export the lists, and walk you through the handoff. Nothing gets ransomed.

Which verticals do you run?

InboxRev is built exclusively for B2B technology companies. We have running playbooks across custom software development, SaaS, IT services, and adjacent tech verticals. If your segment is one we have not run before, we will tell you on the call. We would rather lose the deal than run a campaign we cannot win.

Do you work with competitors in my space?

No. One client per ICP sub-segment per geography. If we are already running your direct competitor, we tell you on the first call and do not sign you. An NDA is standard on every engagement.

Can I see performance in real time?

Every client gets a read-only login to our dashboard. Domain health, sending volume, reply rate, positive replies, and warm intros delivered. Live, not a Friday slide deck. API access is available for any team that wants to pipe the data elsewhere.

Who actually runs my campaign?

Senior operators inside InboxRev. Not offshore freelancers, not a revolving door of account managers. The founders are in every account at some level, and you meet the operator running your account during kickoff.

Is the 95% inbox placement number real?

It is real and it is in the contract. We hit 95% primary inbox placement across our portfolio using isolated sending domains, 14-day warm-up, a strict per-inbox daily send ceiling, correctly configured SPF, DKIM, and DMARC, and regular seed testing. No secrets, just the fundamentals executed without deviation.

Is cold email even legal?

Yes. B2B cold email is legal in the US under CAN-SPAM and in the EU under GDPR's legitimate interest provision, as long as the data is publicly sourced, every email includes a clear opt-out, and the message is relevant to the recipient's role. We source through compliant, ISO-certified data platforms and comply on every send.
