CampaignStack vs lemlist (2026)

CampaignStack

by CampaignStack

lemlist

by lemlist

Pros

• ✓Auto-send and human review are separate workflow nodes, so each campaign can be set to run unattended or to pause for approval.
• ✓Publishes a first-party MCP server with Bearer key authentication, so external AI agents can drive campaigns without the UI.
• ✓Every feature is included on the paid plan, with credits rather than tiers governing volume, and unused credits roll forward for six months.

Limitations

• ⚠Automated sending runs on a stored LinkedIn session cookie, and the vendor's terms make the customer responsible for not violating LinkedIn's own terms of service.
• ⚠Nine of the sixteen listed integrations are roadmap items and Apollo and HubSpot are in beta, so only LinkedIn, Sales Navigator, Instantly, Gmail, CSV and webhooks are live.
• ⚠The overage rate is published as $0.0035 per credit in the credits section and as $0.035 per credit in the pricing FAQ, a tenfold difference the vendor has not reconciled.

Pros

• ✓The Email plan is priced for unlimited users rather than per seat. At $55/month billed annually the whole team shares one rate, and the plan scales by send volume rather than by headcount. Multichannel is the per-user tier at $87.
• ✓AI Variables generates a unique icebreaker per prospect from a single prompt, with no manual research per contact, and Intent Signal and Data Enrichment Agents handle sourcing and enrichment end to end.
• ✓Publishes an official MCP server at app.lemlist.com/mcp, included on every plan, plus a library of 38 free Claude skill files covering ICP definition through sequence analysis.
• ✓Publishes an actual SOC 2 Type 2 report through its trust center, alongside 77 documented security controls, rather than an unqualified compliance badge.

Limitations

• ⚠Multichannel is priced per user with no volume discount, so cost scales linearly with headcount at $87 per user per month on the annual rate.
• ⚠LinkedIn automation lags dedicated tools. Safety controls and campaign complexity are less mature than platforms built specifically for LinkedIn outreach.
• ⚠Contact data is metered separately from the subscription. lemlist credits cost $0.01 each, a verified email costs 5 credits and a phone number 20, so a $10 pack of 1,000 credits covers about 200 emails or 50 phone numbers.
• ⚠The Email plan entry rate covers 50,000 emails per month. Higher volume is a separate price step rather than an overage, rising to $89, $159, $359 and $659 per month at 100,000, 200,000, 500,000 and 1,000,000 emails on monthly billing, or $71, $127, $287 and $527 billed yearly.
