Your marketing manager is leaving. Here's everything they can still touch.

The marketing estate, mapped

• Social: Facebook Page and Instagram (via the Meta Business portfolio), LinkedIn Company Page, TikTok, YouTube, X — each with its own admin list.
• Email marketing: Mailchimp/Klaviyo/Brevo — who owns the account, and whose card pays for it?
• Analytics & tags: GA4 and Tag Manager access; the pixel and its datasets.
• Ads: Meta ad accounts, Google Ads, LinkedIn Campaign Manager — and the payment methods inside each.
• The long tail: Canva, link shorteners, scheduling tools (Buffer/Later), landing-page builders, webinar platforms, stock-photo licences — the tools nobody else has ever logged into.

Before their last day

1. 1
   Walk the list together

   One hour with the departing manager and the list above: for each item — who owns it, who else can get in, what renews on which card. You're filling the register you should have had.
2. 2
   Transfer anything they own outright

   Email platform under their login → transfer ownership (see the Mailchimp guide). Instagram tied to their phone → move it into the Business portfolio. Tools on their card → company card.
3. 3
   Add a second admin everywhere

   Every platform above should end the week with a current employee holding admin alongside them.
4. 4
   Re-point recovery contacts and 2FA

   Recovery email/phone on socials and tools moves to company-controlled contacts — this is the step everyone forgets and regrets.

Departure day and after

1. 1
   Remove their access platform by platform

   Portfolio, Page, LinkedIn, email tool, GA4, ads, the long tail. The general offboarding checklist's departure-day list applies verbatim.
2. 2
   Rotate every shared password

   Marketing teams share logins more than any other function — assume anything in the shared vault is known.
3. 3
   Watch the 30-day window

   Scheduled posts from their account, billing failures on removed cards, vendor emails to their dead inbox — the marketing stack fails on a delay.
