Have a mailing list or emailing service – Create an opt-in form for your readers to sign up on so you can have their contact information readily available. You’ll want this in order to advertise plumbing leads and be able to follow-up with them at the appropriate time.
Find sources of free advertising like websites, blogs, social media platforms and other online communities where plumbing companies may post job openings or where people are looking for services from plumbers
Consider partnering with another business – If there is another company that also offers plumbing services but has similar marketing goals as you do, consider working together toward mutual success through joint promotions and cross-marketing opportunities. For example, if both of your companies offer water heater installation services, you could offer a discount on water heater installation for customers who sign up to your mailing list.
