Why Agencies and High-Volume Senders Stick With Primeforge
"Smart, stable, and flexible — exactly what we needed."
"We use Primeforge together with Warmforge for Rippla’s outreach. Our Gmail accounts are created in Primeforge and warmed up in Warmforge, then connected to Kommo and in-house automation scripts — and they just run smoothly.
We send both CRM follow-ups (for leads who didn’t finish onboarding) and separate campaigns to new businesses using our own Python script and Google Sheet.
Integration is simple, deliverability is very high, and support is flexible and responsive when we need help. For us, Primeforge became a reliable hub for automated communication at scale."
"Effortless Cold Email Setup, But Needs More Transparency"
"It is the technical backgrouWhat stands out is how hands-off the setup is. Primeforge takes care of all the technical deliverability details — SPF, DKIM, DMARC, domain warm-up, and DNS records — without me needing to touch anything. The mailboxes come pre-configured with US-based IPs, which gives a strong deliverability baseline right out of the gate. It’s basically “cold email infrastructure as a service,” which saves a ton of time compared to managing dozens of inboxes manually. I also like that they let you add profile pictures to the mailboxes — it’s a small detail, but it makes outreach emails look more legitimate and personal.nd which makes.”
"Say Goodbye to Email Setup Headaches"
"I love how easy it is to add new domains and mailboxes, and the workspace feature keeps everything organized. Using US-based IP addresses seems to help my emails get delivered, and the ESP Matching is a nice touch - it feels like my messages are more likely to be seen."
