2026 Integration Guide

GTMS + Apollo

Apollo.io is a sales intelligence platform with a 290M+ contact database, email sequencing, and CRM sync. GTMS adds the signal intelligence layer — so you know which contacts from Apollo's database are actually in a buying moment right now.

What Apollo Does

Apollo is one of the best contact databases in B2B sales. With 290M+ verified contacts, email sequences, and a built-in CRM sync, it gives SDR teams everything they need to build prospect lists and run outreach at volume. Its free tier and affordable pricing make it accessible to teams of all sizes.

What GTMS Adds

GTMS is a signal intelligence layer that sits on top of your contact data. It monitors 44 buying signal types — LinkedIn activity, job changes, hiring signals, content engagement, and more — to surface who in your Apollo lists is showing purchase intent right now. GTMS then automates LinkedIn outreach and multi-channel sequences to act on those signals before competitors do.

How Apollo + GTMS Work Together

Build your prospect list in Apollo using filters, job titles, and company criteria

Import that list into GTMS and let signal detection identify which contacts are showing active buying signals

GTMS automatically prioritizes the hottest leads and triggers personalized LinkedIn + email sequences

Replies and engaged prospects flow back into Apollo or your CRM for follow-up by AEs

Contacts with no signal activity stay in Apollo for future nurture — no wasted outreach budget

Example Workflow

Best For

SDR teams using Apollo for prospecting who want to stop spraying their entire list and start targeting the 10% showing real buying intent. Particularly powerful for teams running outbound at volume who need a smarter prioritization layer.

The Bottom Line

Apollo and GTMS are genuinely complementary. Apollo solves the 'who should I contact?' problem at scale. GTMS solves the 'who is ready to buy right now?' problem. Together they reduce wasted outreach and increase reply rates by ensuring every touchpoint lands when the prospect is most receptive.
