Back in 2013 I've rented a parking slot for 2 days in Paris via a website. They've sent me two emails back than - a welcome one and a payment confirmation.
But now I've got one more regarding their new deals for a long-term parking:
Might this be interesting for me? No. Why? Because I used your service only once, it was a short-time rental, and it was year and a half ago!
What kind of a customer this email had to be sent to? For a long-term customer who has been buying during last couple years. For a mid-term customer who has been buying recently.
