Reacher review
A strong fit for teams that want Docker-based self-hosting and API verification.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Reacher is an email verification service for developers and teams that need to assess address deliverability, clean email lists, and reduce bounces. It combines a web dashboard with a REST API for individual checks and bulk verification through API jobs. Results include reachability classifications—safe, risky, invalid, or unknown—along with disposable-address, role-account, MX, SMTP, syntax, and normalization details. Its strongest audience is teams that want an open-source deployment option rather than a hosted-only service.
The self-hosted open-source offering is free and available under the AGPL-3.0 license. Teams choosing hosted SaaS can select the SaaS 10K Emails Plan at €69 per month, which includes 10,000 email verifications, Reacher-hosted infrastructure, and email and chat support. The Commercial License costs €699 per month and adds unlimited verifications, bulk email verification, self-hosting on customer-purchased servers, no data sent back to Reacher, and email and chat support. SaaS plans do not include a free trial, while the Commercial License includes a trial with a daily limit.
Reacher fits workflows built around web, API, or self-hosted environments, with integrations listed for Mailchimp, HubSpot, and CRM systems. Proxy support for SMTP verification adds deployment flexibility, while the combination of Docker, API access, and risk classifications supports both individual checks and list-cleaning jobs. The trade-off is focus: teams seeking real-time form verification should choose an alternative, and organizations that do not need self-hosting may find the €69 monthly hosted plan a narrower fit than a service designed around their preferred workflow.
