CTD builds your network from your email history. Connecting a personal Gmail or Outlook account alongside your work email gives CTD more signal — surfacing contacts and relationships that don't appear in your work inbox at all.

Why connect a personal email?

Your work email captures your current professional relationships. Your personal email often captures deeper, longer-standing ones — friends who've since become relevant professionally, advisors you correspond with on a personal address, or contacts from earlier in your career. Adding a personal account means those relationships show up in your network score and are available as warm paths.

How to add an account

  1. Go to app.ctd.ai/accounts.
  2. Click Add Google account or Add Outlook account.
  3. Complete the OAuth flow to authenticate.
  4. Choose your read access scope (see below).
  5. Optionally enable Send permission so CTD can send ghost emails from this address in one click.

Once connected, CTD syncs your email history, enriches and scores your contacts, and deduplicates them against any other accounts you've connected. Your network score updates automatically.

Read access scopes

When connecting an account you choose how much access CTD has:

  • Metadata only — CTD reads the email envelope: from, to, cc, date, and subject line. No email body. Maximum privacy, still provides relationship data.
  • Emails with signatures — CTD reads metadata plus email signatures, which it uses to extract job titles, phone numbers, and other contact details to enrich your network. This is the recommended setting for the richest data.

Send permission

Send permission allows CTD to send ghost emails from this account the moment you approve a draft — without you having to open your email client. You can toggle this on or off at any time from the Connected emails page.

CTD never sends emails on your behalf without your explicit action. Send permission only activates when you actively approve a ghost email request — CTD will not send anything automatically.

Primary account

One account is marked as your primary — this is the address that receives CTD notifications and powers outreach. You can change which account is primary at any time.

What CTD reads from your email

CTD never reads the body of your emails. Both scopes include email headers (from, to, cc, date, subject); the Emails with Signatures scope additionally reads signatures for contact enrichment. See What data does CTD collect? for the full breakdown.

Removing an account

Go to app.ctd.ai/accounts, click the ⋮ menu on the right side of the account row, and select Delete account. Removing an account removes the relationship data sourced from that inbox from your network graph.
