For email marketing agencies
Last updated: August 2026
Email and lifecycle agencies lose hours to shared Klaviyo and Mailchimp logins and the new-device verification loop. Proper user access ends it. Manually, that's a 3–5 email chain per platform, per client — the slowest, least professional part of any kickoff.
Your client approves access to Klaviyo, Mailchimp and HubSpot through each platform's official process, in about three minutes. You're added as a partner or user — never a login — so there are no lockouts. And because the client keeps a control panel, they approve faster and offboarding stays clean.
