I've been quiet for a few weeks. Not because I ran out of things to say. Because I was rebuilding my entire cold email process from scratch. Here's what changed: Infrastructure: Switched to Peeker AI for all my email accounts. Why? Self-healing inboxes. When reply rates drop, they automatically replace the domain. For free. No more manually tracking why inboxes are dying.

Stories From Teams Scaling OutreachWithout Spam Issues

Lead Generation Agency Owner
Prior to Peeker, I was using other inbox providers and it took over 2 weeks to warm up inboxes and 4 days to set up, meaning almost 3 weeks to set up campaign inboxes. Support was also very slow in getting back. With Peeker, the pricing is amazing, the inboxes are reliable, and the support is great.

"It's been great using Peeker so far. We've been trying to diversify our inbox infrastructure for a while and discovering Peeker has been a game changer. We test ran a new campaign with Peeker inboxes and got a 4% increase in reply rate compared to our manual inboxes."
Clark Gonek
Head of Growth, Boardy AI
"I'm mostly big on Google inboxes and I have experience with Azure inboxes using other inbox infrastructure but there was not much attention to detail unlike Peeker. With Peeker's Azure inboxes, we're sending about 5,000-6000 emails per day which is great for the price point."
Floris Jansen
Founder, Vectify
"Reply rates and inbox burn was an issue with previous inbox providers. I was looking for a new provider, stumbled on Peeker's website, and booked a call. The mailboxes and deliverability are good but the communication, setup time, and inbox swaps response time is great."

Proud to say LeadGenXperts is now a Peeker AI deliverability expert partner. There are a lot of infra providers in the market and honestly I was confused whom to go with. I'm not a techy, more of a marketer. I just wanted something that solves my technical problems without me having to babysit it. Tested a few providers. They were all fine. Then a friend suggested Peeker. Thought it'd be the same as the rest. But then I talked to the founder and he mentioned their inboxes have self healing power.
Boardy AI scaled from 6K -> 15K cold emails a day... With ZERO deliverability decay. Their problem was all too common: Running outbound through Google infrastructure with no visibility into what was breaking And as a result: - Inboxes went down constantly - Had to pay to rebuild them - Zero proactive monitoring - Bounce rates sitting at 4%
