CampaignStack vs Sanity (2026)

CampaignStack

by CampaignStack

Sanity

by Sanity.io

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

• ✓Content Agent, Agent Actions and Agent Context are included on every plan, including Free, with 1,000 AI credits a month.
• ✓An official MCP server lets AI clients such as Claude, Claude Code, Cursor and Lovable create projects, migrate schemas, run bulk edits and query content.
• ✓Sanity holds its own SOC 2 Type 2 report, lists GDPR and CCPA compliance on every plan, and hosts its backend in the EU (Belgium).

Limitations

• ⚠SAML single sign-on, custom roles, content releases and the full audit trail require the custom-priced Enterprise plan.
• ⚠A Content Agent query uses 4 AI credits and each action 2, and on Growth credits beyond the 1,000 included each month cost $0.05 each.
• ⚠Free plan datasets are public only, Comments, Tasks and scheduled drafts start at Growth at $15 per seat per month, and Growth is capped at 50 seats.
