Open Letter Marketing

Open Letter Marketing is a mail house that also supplies the strategy and software around a campaign: audience and mailing lists, creative, print production, campaign execution and integrations back into the client's own systems. It grew out of direct-to-seller real estate investing and still serves investors and agents, alongside home services trades, professional and financial firms, marketing agencies and ecommerce sellers.

The catalogue runs from postcards in 4x6, 6x9, 6x11 and 9x12 sizes, with optional Street View imagery and a printed offer, through printed letters, snap packs and tri-fold flyers, to real penned letters written with an actual blue ink pen by the company's writing machines, including the envelope addresses on the professional version. Multi-touch campaigns of three to six touches can be assembled from preset templates or built to a custom cadence and then mailed on schedule.

Open Letter Connect is the automation layer, triggering mail from a CRM, ecommerce platform, marketing workflow or internal software. Campaigns come with marketing coaches rather than being purely self-serve, and the company says it is trusted by more than 1,000 companies and lists an Inc. 5000 placement.

Per-piece prices appear on individual product pages, with Snap Pack Check Mailers listed at $1.05 each. List costs, postage class and volume all move the real number, so price a specific campaign rather than working from a single unit rate.
