How a Gmail and Klaviyo automation gets built
- Describe the outcome. Say what should happen — not which endpoints to call. HumDay works out which operations each side needs.
- Approve the contract. Before anything is built you see exactly what it will do in Gmail and Klaviyo, and what it will never do.
- See it proven. The program runs and shows you the result before it is allowed near either live account.
- Grant access, then go live. You approve the specific operations it may use on each side — and only those.

Questions about connecting Gmail and Klaviyo
- Can Gmail connect with Klaviyo?
- Yes. HumDay reads both providers' own published API descriptions and derives what each one can do, so neither side needs a hand-built connector before you can use it.
- How do I connect Gmail to Klaviyo?
- Describe the outcome you want in plain words. HumDay agrees a contract with you saying exactly what it will do, writes the program, and shows you a proof run before either account is touched.
- Do I need to write code to integrate Gmail and Klaviyo?
- No. There is no node graph to wire up and no field mapping to do. You say what should happen and HumDay works out which operations it needs from each side.
- What can HumDay do across Gmail and Klaviyo?
- Gmail publishes 79 documented operations and Klaviyo publishes 345. HumDay only ever uses the specific ones your approved contract needs.
- Is it safe to connect both accounts?
- Your credentials are stored encrypted and never appear in chat, code, or logs. Anything that writes to either Gmail or Klaviyo is held behind an approval you grant explicitly.
