Definitely if in you marketing plan one of the strategies is reach people through the feelings, you should use a post mail for contact your potencial public or clients.
Today i’ve received a postal mail… yes! an envelope! (and were not invoices). Was a invitation for a event organized for a company that sell machines to purify the water. They’ve organised a event to show ‘in live’ the properties of their product.
I think is a good marketing action these days an old practice coming alive again.
Don’t forget to add a link to your web site, social media profiles and invite to read a qr code. This will help you to optimise the action and to be able to measure the results.
Is it for you a valid kind of marketing nowadays?
