About

LetterFriend is a direct mail and handwritten letter service that helps organizations create personalized, real-handwritten notes, envelopes, and cards, crafted by professional writers rather than fonts, robots, or printers, to cut through digital noise and strengthen customer relationships, referrals, and pipeline growth through high-impact physical outreach. The platform lets users upload contact lists via CSV or integrate with CRM systems, Zapier, or an API to automate and scale campaigns, whether sending thank-you letters, prospecting notes, holiday cards, or other personalized correspondence that is hand-addressed, handwritten, and mailed on behalf of the customer. LetterFriend emphasizes human-touch direct mail with real people in New Jersey writing each word, delivering consistently higher open and response rates compared with typical printed or email outreach, and offers customizable options such as envelopes, sticky notes, signatures, postcards, etc.

About

PostKnock is a marketing platform for small service businesses — dental practices, HVAC contractors, optometrists, chiropractors, veterinary clinics, and home services. It combines direct-mail postcards with automated phone follow-up in a single workflow. Choose a pre-built industry playbook (dental recall, HVAC seasonal, lapsed-patient re-engagement, etc.), upload a contact list, and PostKnock handles printing, USPS First-Class mailing, QR-code tracking, and post-delivery call queues with pre-loaded scripts for your front desk. Multi-wave campaigns sequence postcards and calls over weeks. CSV import auto-maps fields. Real-time tracking shows delivery, scans, completed calls, and revenue attribution. Free plan available — only pay for postcards sent. Pro from $99/month unlocks multi-wave sequencing, the full call queue, and analytics. No contracts. 30-day money-back guarantee.
