Complete contact information
Phone, email and service address. Records without contact data can't be reactivated.
Equipment records
Brand, model, install date and service history. These details power replacement and maintenance campaigns.
Useful tags
Tags like membership, equipment age, property type and service area let you send relevant messages.
Permissions
Track who agreed to receive texts and emails. Respect opt-outs immediately.
Regular cleanup
Schedule a monthly check for duplicates and missing fields.
One owner
Assign someone in the office to own data quality. Shared responsibility means nobody does it.
Train the team
Techs and CSRs must enter data the same way every time.
Where to start
Export your list, sort by name and phone, and merge the obvious duplicates. Then fill in missing equipment data on your top 100 customers.
Know your numbers
Track the percentage of records with phone, email and equipment data. Raising those numbers raises campaign results.
Common mistakes
Importing old lists without cleaning, letting each person enter data differently and ignoring opt-outs.
