Sendlane for AI agents
Sendlane is a marketing automation platform built for ecommerce brands, combining email and SMS campaigns with subscriber lists and tagging. Ecommerce marketers use it to run lifecycle messaging. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.
What agents do in Sendlane.
Review campaign performance
Pull the current campaigns and their custom fields to see what is live before launching something new.
Tag a subscriber segment
Create a tag to mark a group of subscribers for a targeted email or SMS sequence.
Confirm before removing a list
Check a list's details and get sign-off before deleting it, since removing a list can't be undone.
6 Sendlane actions, graded by risk.
Every Sendlane action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

Sendlane in three steps.
- 01Your users connect SendlaneThey add their Sendlane api key on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, writes like “create List” can wait for the user, and “delete List” can be denied outright.
- 03Any agent can actYour agent calls Sendlane through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('sendlane', { read: 'allow', write: 'ask', // post_list destructive: 'deny', // list_delete }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How Sendlane connects.
Users add their Sendlane api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.
The same Sendlane connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →
- AUTH
- API key
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES
- Results only, never credentials
- AUDIT LOG
- Every call, on every plan
Use Sendlane from any agent.
Sendlane and Arc0, answered.
Can I use Sendlane with Claude, ChatGPT or Cursor?
Yes. Connect Sendlane to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Sendlane actions you allow.
How do users connect Sendlane?
Users add their Sendlane api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.
Which Sendlane actions can my agent take?
6 in total: 3 read, 2 write and 1 destructive, such as “create List”. Your policies decide which of them each agent may call.
Can I stop my agent from deleting things in Sendlane?
Yes. Actions like “delete List” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.
Can my own backend call Sendlane too?
Yes. The same Sendlane connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Sendlane into your agent.
Your users connect Sendlane once, under your brand. Your agent gets 6 actions behind your policies, with every call on the record.
