TGP·B2B prospecting agency (LATAM)TL;DR
TGP, the largest prospecting agency in Latin America, was bleeding ops hours stitching together domains, Google Workspace, and email creation across five separate vendors. On InboxKit, that whole chain collapsed into a few clicks — dropping client onboarding from hours to minutes without touching their 15.2% reply rate.
TGP, the largest prospecting agency in Latin America, runs outbound campaigns for some of the largest companies across the region. They know cold email. They know regional strategy. They know how to convert. But they were bleeding time on something that had nothing to do with strategy: mailbox infrastructure.
Before InboxKit, setting up a single client mailbox meant buying a domain from Namecheap, creating a Google Workspace account, connecting the domain manually, generating individual email inboxes, then integrating everything into their platform. Multiply that by hundreds of clients across multiple regions, and you are looking at weeks of ops work every month.
Samuel Weinstein, CEO, received a cold email from InboxKit. He forwarded it to Francesco, the ops lead responsible for this chaos. Francesco took a meeting. Two weeks later, new mailboxes were provisioned in minutes.
TGP's mailbox workflow was fragmented across five separate vendors and manual steps.
Francesco was spending hours on repetitive work that should have been automated. There was no way to onboard a new client quickly without bottlenecking on infrastructure. Every domain purchase, every Workspace setup, every email creation was a separate transaction.
For an agency trying to scale regionally, this wasn't just slow. It was a ceiling on how many clients they could support.
Before InboxKit, we had to buy domains from Namecheap or GoDaddy, set up Google Workspace, connect the domain, then create the emails. Google Workspace configuration is hard and slow. We bought the domain, then the Workspace, then connected the tool, then generated the email accounts, then connected those to our platform. Francesco was doing this all by himself. — Samuel Weinstein, CEO
Samuel forwarded the InboxKit email to Francesco. That conversation changed how TGP operates. Here is what changed, step by step:
With InboxKit's Standard product — mailboxes, domains, warm-up, and DNS automation — the time to onboard a new client dropped from hours to minutes.
All of that is now done with a few clicks. Francesco is the one who is the happiest because he was doing this all by himself. — Samuel Weinstein
TGP's campaigns on InboxKit achieve a 15.2% reply rate and maintain a 0.7% bounce rate. They are sending 80K emails per week across their client base, with strong deliverability indicators across regions.
More important than the metrics: the ops constraint is gone. Francesco's time is freed from domain and workspace setup. New clients can be onboarded in minutes instead of days. TGP is systematically migrating remaining legacy infrastructure to InboxKit.
The pricing is way, way cheaper. We have many more accounts to migrate to InboxKit, and we will. — Samuel Weinstein
One platform, not five. TGP no longer coordinates between domain registrars, Google Workspace, email clients, and integration tools. Every subscription they managed separately is now consolidated. Context switching is gone. Data stays consistent.
Speed unlocks capacity. When infrastructure setup goes from hours to clicks, ops teams move from firefighting to strategy. For a scaling agency, that means faster client growth without hiring more ops staff.
Deliverability people trust. A 0.7% bounce rate and consistent 15.2% reply rate across regions mean clients see predictable performance. That's not luck. That's why TGP keeps migrating.

Case StudyIn late 2025, a Google mailbox crackdown ran through the cold email world and hit agencies hardest. Rather than chase the next cheap workaround, Jayson DeMers of OutreachBloom moved to InboxKit mid-crisis — and has run OutreachBloom's cold email infrastructure on it ever since, at an 11.5% reply rate and a 0.6% bounce rate.
Case StudyManaging 100+ client campaigns at scale meant abandoning manual infrastructure work. InboxKit's automation became the only way forward — automated DNS (zero manual hours), domain isolation, zero suspensions, and a 17% average reply rate.
