Automate outreach on six channels, not two.

Passive candidates ignore a single channel. You email, maybe you send an InMail, and the people worth hiring — already employed — never reply. Email reply rates keep sliding, and if your tool only automates one or two channels, every extra touch becomes a manual to-do someone has to remember.

For an agency the seat math compounds it: per-seat or per-FTE pricing means you pay for headcount whether or not a recruiter is on a live req. Reaching candidates where they actually reply, and automating it, is the difference between a cadence that runs and a list of reminders.

Reply-rate trends reflect widely reported market conditions; verify against your own channel data.

Gem is a mature all-in-one recruiting platform. It pairs an ATS, a CRM, sourcing, scheduling, and analytics, and more than 1,200 companies run on it (gem.com, as of June 2026). ATS Candidate Rediscovery is a Gem flagship: Gem reports that 44–46% of hires come from candidates a team already had (gem.com, as of June 2026). Reviewers rate its email reply sentiment well for accuracy, and its database holds 800M+ profiles, larger than ours (gem.com, as of June 2026). On G2, Gem rates around 4.7–4.8 (g2.com, as of June 2026).

If you want one vendor for the whole hiring funnel and the biggest database in this comparison, Gem is a strong choice, and we will tell you so.

Gem automates email and SMS; inside a Gem sequence, LinkedIn InMail, connection requests, and phone calls are manual reminder steps, and we found no published WhatsApp, Telegram, or automated voice (help.gem.com, as of June 2026). MartyHR is built to automate all six — email, LinkedIn, SMS, WhatsApp, Telegram, and voice — in one sequence with conditional triggers, so no channel depends on a recruiter remembering to do it.

Three more reasons agencies and EU teams are joining the list:

• Billed per connected account, not per seat or FTE. Gem prices per user (staffing) and per FTE (in-house) (gem.com/pricing, as of June 2026). Account-based billing maps to how an agency runs several senders across several clients.
• One cross-channel inbox, with sentiment across channels. Gem Messages is SMS-only and its reply sentiment is email-only and binary (help.gem.com, as of June 2026). MartyHR threads every channel into one inbox, tagged positive, neutral, or negative.
• Your network and HRIS, plus a score you can read. MartyHR searches your team's first-degree network and your HRIS (e.g. BambooHR) alongside your ATS, and marks every criterion found, potential, or no evidence into a 0–100 fit score. (Pre-launch, designed to spec.)

Choose Gem if you want one vendor for the entire hiring funnel (ATS, CRM, sourcing, and scheduling), the largest database here, or a tool you can buy and run today. Gem is the more complete platform, and for those teams it is the better fit.

Choose MartyHR if you are a recruiting agency or an EU in-house team that wants automated outreach across six channels, billing tied to connected accounts rather than seats, and search that reaches your team's network and HRIS. Join the launch list and early joiners lock in design-partner pricing and a direct line on the roadmap.
