Apex Overlay for Instantly.ai
Get more replies from the same campaigns — automatically
Apex Overlay connects to Instantly.ai and sends more volume through whichever email variants are actually getting replies. No manual A/B testing. No campaign changes. Just more replies from the same lists.
Your campaigns, inboxes, and sequences stay untouched. Only the send distribution changes.
The Problem
Your data got better.
Your testing didn’t.
75% of sends go to emails that stopped working
Standard A/B testing splits sends equally. Your worst email gets the same volume as your best — and you only find out after the leads are burned.
Yesterday’s winner is today’s loser
Reply rates shift week to week. By the time you check your dashboard and manually pause a variant, hundreds of leads have already seen your worst copy.
Different buyers need different emails
A CTO and a VP of Sales respond to completely different angles. But who has time to test copy for every segment?
Half your “opens” are bots
Security scanners, link crawlers, and email filters inflate your data. You’re making copy decisions based on signals that aren’t real.
Apex Overlay fixes all of these automatically.

FAQ
Top questions
No. Apex Overlay sits on top of Instantly. Your campaigns, inboxes, warmup, and sequences stay exactly the same.
No — it helps. By dialing down emails that get ignored and sending more of what gets replies, your overall engagement improves. Better engagement means better sender reputation.
The more variants & sends the better, but the algorithm works best with at least ~600 sends per week. Below that, learning just takes a bit longer.
Every open, click, reply, and spam report is tracked in real time. Bot activity is filtered out automatically so only real human engagement counts. Emails that get genuine replies earn more sends. Emails that get ignored or flagged get fewer.
