Email and SMS campaigns for a roofing company
Roofing owners assume a customer list is worthless because a roof lasts 25 years. The list is not for repeat roofs. It is for referrals, for the gutters and siding you already had a ladder up for, and for estimates you never closed.
Two campaigns do the work. A quarterly note to past customers with one seasonal item, which produces referral calls at almost no cost. And a revival campaign to unsold estimates from the last 18 months, which usually books something in week one. The mistake is a monthly newsletter nobody reads.
