Grassfed vs doing Just Sold emails yourself in Mailchimp
Mailchimp is excellent for emailing people who opted in, like your past clients and sphere. But its Acceptable Use Policy prohibits sending to purchased, rented, third-party or publicly available lists, so cold-emailing neighbors from Mailchimp isn't allowed. Grassfed, an MLS-synced AI agent for Just Listed / Just Sold, is built for that job: it sends a short, plain-text 2-email sequence to the nearest neighbors, the first emails start within 6 hours of your listing or sale, it runs on Grassfed's managed sending infrastructure, and replies reach your own inbox.
For why Constant Contact and brokerage email suites have the same limit, see Why Mailchimp, Constant Contact and brokerage email tools don't work for cold email.

Who each fits

How they work
Mailchimp DIY. Build a list of contacts who opted in, design a Just Sold email, and send it or automate it. Mailchimp's policy requires evidence of consent and prohibits purchased or third-party lists (https://mailchimp.com/legal/acceptable_use/).
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. Grassfed finds the nearest homeowners' emails and sends a short, plain-text 2-email sequence, starting within 6 hours (https://www.grsfd.ai/faq). 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 it follows CAN-SPAM (https://www.grsfd.ai/faq).
Cost comparison
- Mailchimp: plans scale with contact count. See the live pricing page (https://mailchimp.com/pricing/marketing/).

When Mailchimp is the better choice
- You're emailing past clients, your sphere or newsletter subscribers who opted in.
- You want full control of design, segmentation and automations.
