Armada vs Warmbly

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

Starting price

Armada

Quote-based

Armada is a cold email platform for agencies whose clients sell to local businesses, combining Google Business Profile lead sourcing, owner discovery and sending across your own mailboxes. It is in early access with pricing set on a call, so treat it as a young product.

Where Armada fits

  • Lead generation agencies selling to local businesses
  • Agencies running cold email for several clients
  • Teams that already own many sending mailboxes
  • Outbound teams that follow email with phone calls

Warmbly

$29/mo 14 day free trial

Open-source cold email platform that bundles warmup, unlimited mailboxes, a labelled reply inbox and a map-based local lead finder. Cloud plans price by daily sends from $29 a month with a 14-day free trial, and agencies that want to own the stack can self-host the whole thing free.

Where Warmbly fits

  • Staffing agencies giving each recruiter their own warmed mailbox
  • Teams that want unlimited mailboxes without per-inbox pricing
  • Agencies prospecting local small businesses by area
  • Technical teams that want to self-host cold email

Where they pull apart

Armada

Stands out: It sources leads from Google Business Profiles and company websites instead of a LinkedIn-shaped database, which suits trades, clinics and shops, and every owner contact carries a confidence level. It also adds a phone caller queue and per-client portals on top of the sending, with no markup on sends because you use your own inboxes.

Watch out: Pricing is not published and the product is in early access, with no outside reviews yet. You need your own Google Workspace, Microsoft 365 or SMTP mailboxes unless you buy the Done for you service, and it is aimed at local business prospects rather than corporate or recruiting targets.

Not the right fit for

  • Recruiters prospecting corporate hiring managers
  • Buyers who want a published price
  • Teams with no sending inboxes of their own

Warmbly

Stands out: It is the only full cold email platform in the directory whose sending, warmup and health rules are public code under Apache 2.0, so an agency can read why a mailbox was slowed or run the whole thing on its own server. Paid plans charge by daily send volume with unlimited mailboxes and no seat fees, and the built-in lead finder turns a drawn map area into named owners with checked addresses ready for a campaign.

Watch out: Self-hosting is free but its warmup only pairs the mailboxes on your own instance, with no shared pool and community-only support, so for deliverability the paid cloud is the real product. The Starter plan caps you at 150 cold emails a day, and the CRM, API and A/B tests start on the $89 Grow plan. The lead finder reads small business websites, so it suits local and SMB prospecting rather than finding hiring managers at larger companies.

Not the right fit for

  • Teams needing a large B2B contact database built in
  • Prospecting named decision makers at enterprise companies
  • Non-technical users wanting free deliverability from self-hosting

What each one costs

Armada

Quote-based

Armada is in early access and does not publish prices; Solo (one company workspace) and Agency (unlimited client workspaces, client portal, roles) are both priced on a short call, and early access customers get locked-in rates. A Done for you service, where Armada's team sets up domains and inboxes, builds lists, writes copy and runs replies, is custom priced. There is no per-email or per-lead charge because sends go through mailboxes you already pay for. Confirm current terms on the vendor site.
