$49/mo Free tier Free trial MCP API
Why it comes up: Apollo is a contact database and sequencer from $49/user/mo, not AI-personalized video.
Stands out: A large people database plus email sequences in one login, with MCP and a Chrome extension.
Watch out: Data quality varies by segment, and it does not match enterprise tools for intent data and org charts.
Best for
- Outbound recruiting and sales on one database
- Teams that want free-tier access to start
- Desks that need sequences next to the data

$47/mo Free trial MCP API
Why it comes up: Instantly is high-volume cold email from $47/mo with warmup, without SendSpark's dynamic video.
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 agency cold-email infrastructure from $39/mo, not personalized video.
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

$35/mo 14 day free trial MCP API
Why it comes up: Woodpecker is agency-friendly cold email from $35/mo if you do not need video personalization.
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
