$47/mo Free trial MCP API
Why it comes up: Native CRM sync may be enough if Instantly is your only sequencer.
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: Sequencer with its own CRM connections if you stay in one tool.
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

$167/mo Free tier 14 day free trial MCP API
Why it comes up: Outbound data ops in a table if a dedicated sync is out of scope.
Stands out: 150+ provider waterfall plus Claygent on every row, with MCP and API.
Watch out: Not a sender. Paid plans start at about $167/mo, with Launch from $185/mo, and credit burn adds up.
Best for
- Sourcers building enriched spreadsheets
- Teams chaining many data vendors
- Desks that want Claygent research columns

$19.99/mo Free tier 14 day free trial MCP API
Why it comes up: Generic automation when volume is low and you accept task fees.
Stands out: Zapier MCP is on every plan, including Free, and connects AI assistants to the same 9,000-app catalog.
Watch out: Each MCP tool call uses two tasks. Free Zaps are limited to two steps, and Professional is a single-user plan.
Best for
- Ops teams connecting SaaS apps without code
- People who want Claude or ChatGPT to act in Gmail and Slack
- Solo users who fit on one Professional seat
