$47/mo Free trial MCP API
Why it comes up: Instantly is a cold-email sequencer with warmup and unlimited sending, not a 20-recipient Gmail tracker at $15/user/mo.
Stands out: Warmup, unibox, and volume send with hosted MCP and a public API.
Watch out: Deliverability still depends on your domains and inboxes, not the tool alone.
Best for
- Outbound recruiting teams sending at volume
- Agencies running many sending accounts
- Desks that need warmup plus a unibox

$39/mo Free trial MCP API
Why it comes up: Smartlead is a multi-inbox outbound platform, a better fit when Yesware's 10-20 recipient caps are the blocker.
Stands out: Unlimited mailboxes plus separate client workspaces, with a hosted MCP.
Watch out: Email only: there is no LinkedIn channel and no finder in the same login.
Best for
- Agencies sending for multiple clients
- Teams that need many mailboxes
- Desks that want MCP on campaign infrastructure

Why it comes up: Mailmeteor is a Gmail mail-merge with a free tier, lighter than Yesware Premium's unlimited campaigns at $35/user/mo.
Stands out: Starter at $5.99/user/mo lifts the cap to 250 emails per day and 5,000 per month, still sending through your Gmail or Google Workspace account.
Watch out: Consumer @gmail.com accounts stay capped by Google at 500 emails per day even on paid plans. Higher volume needs Google Workspace or your own domain.
Best for
- Recruiters sending personalized loops from a Google Sheet of candidates
- Founders who already live in Gmail and do not want a new sender domain
- Schools and nonprofits that can stay on the free daily cap

$35/mo 14 day free trial MCP API
Why it comes up: Woodpecker is a cold-email B2B sequencer with deliverability tooling, not an inbox sidebar acquired by Vendasta.
Stands out: Unlimited team members and mailboxes at no extra cost, since billing is set by how many prospects you contact.
Watch out: LinkedIn costs $29/mo per connected account, and the API, webhooks, MCP and CLI sit in a $20/mo integrations add-on.
Best for
- SDR teams sending cold email at steady volume
- Agencies adding many mailboxes and users
- Teams connecting outreach to Clay or a CRM
