MailLift was posted (www.producthunt.com/maillift) to the community in the first two weeks of PH by @dshan. We received a lot of love from everyone on ProductHunt (including introductions to some of our investors) and wanted to give back.
PS. In case you haven't seen us yet, MailLift integrates handwritten letters, stickers, books and gift cards with Salesforce and marketing automation platforms.
