We have been using MailChimp for the last 4 years to stay in touch with our past clients by email communication. We currently send 4 automated emails, beginning with; a day after cleaning follow up and review asking email, at 2 weeks a referral email, month and half in "did you know about our other services" email, and at 6 months a reminder its time to get their carpets cleaned email, this is all done through the first 6 months, after the clients first cleaning. Then we send 1 monthly email to that same customer every month of the year. How does your company currently use the available Email Marketing Platforms to send to your past clients? Do you send cold emails to potential clients through purchasable lists or some other source? How does it work for you? We are also thinking of adding another email to our monthly email list, which would put us at two emails a month to our past clients. Is this to much? Not enough?
