How J-Reach Achieved 6 Months of Perfect Deliverability with Primeforge

J-Reach helps companies master LinkedIn cold outreach - teaching them how to send 4,000 + targeted DMs every month and generate leads predictably. But while LinkedIn remains their core channel, J-Reach also relies on cold email outreach to fill their own pipeline with high-intent prospects. For that, they needed inboxes they could trust. After testing multiple “premium” providers and facing constant mailbox failures, J-Reach switched to Primeforge - and the difference was night and day.

“Legitimately speaking, the Primeforge email inboxes never fail. After two weeks of warm-up, I’ve never had any issues with bouncing or mailboxes dying out of nowhere for the last six months using it.”

Yap Junte
CEO of J-Reach

The Challenge

As J-Reach scaled their outbound engine, they ran into familiar problems:

  • Mailboxes from other providers started bouncing within weeks.
  • Some inboxes were flagged or throttled mid-campaign.
  • Manual DNS setup and monitoring slowed everything down.

They needed a cold-email-ready infrastructure that could handle high sending volumes, keep inboxes alive for months, and protect their sender reputation.

The Results

Since switching to Primeforge, J-Reach has maintained zero bounce issues and flawless uptime.

No mailbox failures in more than six months of continuous use
Stable inbox placement across all domains
Two-week warm-up completion with no manual effort
Consistent open and reply rates maintained quarter after quarter

The Takeaway

J-Reach runs a multi-channel outbound system where every campaign depends on stable inboxes. With 23 domains and 69 mailboxes powered by Primeforge, they’ve achieved six months of uninterrupted performance - zero failures, zero downtime, zero headaches.

“In terms of having the best mailboxes for cold emails - Primeforge.ai is the absolute best in the market. You never have to worry about your inboxes bouncing all of a sudden.”
