Better email deliverability, faster growth.
MailReach does two things: it warms mailboxes by generating human-like interaction with a network of high-reputation Google Workspace and Office 365 inboxes, and it runs spam tests that report where a given email actually lands per provider. It deliberately does not send campaigns - the vendor's stated position is that deliverability gets sidelined when it is a feature of an all-in-one platform, so MailReach sits alongside your sender rather than replacing it. A REST API covers every workflow in the app.

MailReach is a single-purpose deliverability tool with an unusually complete API for its size. The docs describe a conventional REST surface - JSON in and out, standard status codes, page/per_page pagination in descending creation order - authenticated with an X-Api-Key header carrying a Bearer-prefixed key. The API itself is free; billing is entirely platform usage: a monthly seat per connected inbox for warming and monitoring, and one credit per spam test run. The unit that matters commercially is the account, and the docs are explicit that one account equals one email address: aliases resolving to the same physical mailbox each consume their own seat, because a recipient's provider sees each sending address as a distinct identity.
Teams and agencies whose outbound is already failing on inbox placement, and who want deliverability owned by a specialist tool rather than bundled into their sequencer. The API design - connect inboxes in batch, pull daily stats, subscribe to reputation alerts - points at agencies and platforms managing many mailboxes across clients.
Billing is per connected inbox at $19.50/mailbox/month, and because aliases each count as a separate seat, a team with several sending addresses on one physical mailbox pays for each. That makes the multi-domain, many-mailbox cold-email setups this tool is aimed at genuinely expensive - the vendor's own calculator runs into four figures a month at scale. It also does not send anything: you still pay for a sequencer and, usually, for infrastructure, so MailReach is a third line item rather than a consolidation. Anyone whose sending is low-volume, whose reputation is already healthy, or who simply wants an occasional spam check is better served by the pay-as-you-go credit-only route than by warming seats.
No curated rival set covers this tool yet, so these are simply other tools in the same architectural layer and product form. Treat it as a starting point, not a shortlist.
No. It only warms mailboxes and tests inbox placement. The vendor's stated position is that deliverability is too critical to be an add-on, so it runs alongside whatever sending tool you already use and is compatible with any provider supporting SMTP.
Per mailbox. Warming and monitoring cost $19.50 per connected inbox per month, and spam tests consume one credit per run. The API itself is free to call; you are billed only for platform usage.
Yes, and this is the detail most likely to surprise you at invoice time. The docs state that one account equals one email address, that aliases are counted separately even when they deliver to the same physical mailbox, and that each consumes its own seat - the reasoning given is that a recipient's provider sees each sending address as a distinct identity.
Per the docs, every workflow available in the app: running one-time and scheduled spam tests, connecting and managing inboxes for warming and monitoring, pulling deliverability statistics, and creating alerts.
Eleven documented events: account disconnected, domain expiring soon, new warming mode proposed, account back to normal warming, missing inbound emails, reputation score decrease, reputation score increase, too many messages sent, SendGrid missing emails, Outlook missing outgoing emails, and automated spam test completed. Each can go to a webhook URL or a Slack channel.
No - the docs say so explicitly and advise checking for an existing resource before creating a new one, or updating via the returned id. Webhook deliveries may also be duplicated under failure conditions, so consumers should deduplicate on the event identifier.
The pricing page's plan inclusion list states "Up to 100 emails per day". The vendor describes the activity as organic and human-like rather than canned responses; we have not tested that.
A promotional 20% off the first 30 days of warming a first mailbox was running when we checked. We found no open-ended free tier for warming itself.
Yes, at status.mailreach.co, with automated system monitoring and alerting; it reported normal operation at check time.
