Who each fits
- Grassfed fits agents who want every listing and sale to reach the neighbors the same day, with replies they can answer in their inbox, and who'd rather pay per campaign than per piece.
- Postcards fit agents who want a physical, branded touch in every mailbox (including homes with no known email address), long-term neighborhood branding, or a fixed route-based footprint through EDDM.
How they work
Postcards. Pick a list (or carrier routes for EDDM), design or choose a template, print, and mail. With EDDM Retail, USPS says your mail "will be delivered to every address on your selected routes" (USPS EDDM). Vendors such as ProspectsPLUS! publish per-piece prices that include printing, addressing and postage for mailed cards (pricing).
Grassfed. Connect your MLS ID. Grassfed is an MLS-synced AI agent for Just Listed / Just Sold: it sees the listing address, pulls the nearest neighbors, validates, scrubs and normalizes the data, name-matches homeowners to emails, removes current MLS actives and anyone who moved in within the past 2 years, then builds the campaign and sends it in a human-like, sporadic way over 5 days to avoid spam. When you list or sell, Grassfed emails the nearest homes with a short, plain-text 2-email sequence; the first emails start within 6 hours. Emails go out on Grassfed's managed sending infrastructure, signed with your name and details, which protects your own domain and deliverability (warmed accounts, rotating senders, randomized timing). Replies reach your own inbox: every reply is pushed to you as a notification with the full reply text, and you can also see replies in the Grassfed portal. Grassfed's site states that it follows CAN-SPAM: no deceptive content, a proper opt-out, opt-outs honored, and your office address in the signature (FAQ).
