Tuesday through Thursday are the best days of the week for email and telephone business marketing. Stay clear of any holidays. This is common sense … it’s what you would expect. The national and regional field service firms are not open on the weekend or holidays.
I ran into a person several years ago who was calling field service hiring firms on a Saturday and Sunday. He complained to me that none of the firms were answering their telephones on the weekend. Duh! I didn’t call him stupid … but, I really wanted to unload on this stupid person.
