Contact data changes constantly. Keeping contact details updated improves:
Personalization (better replies)
Deliverability (correct email)
Calling success (correct phone)
Reporting and attribution
Edits apply across Salesgear — meaning if the contact is in a sequence, the updated fields are used going forward.
Step-by-step: Edit a contact
Go to Contacts
Click Options (⋮) for the contact
Choose Edit
Update fields (tags, phone, title, social links, custom fields, etc.)
Click Update Contact
