If your organization already lives in Mailchimp — audiences, journeys, templates, reporting — adding Mandrill blocks keeps transactional email inside a system your marketing team already operates, and that integration is its entire point.
Free: 3,000 emails/month (100/day), 1,000 contacts, 1 domain — no card. Paid from $14/month for 50,000 emails; 100,000 emails from $24/month; Scale at $63/month adds 1,000 domains, priority support, and the dedicated-IP add-on ($21/30 days). Extra volume via credits at $0.90 per 1,000 — they never expire.
Sold in blocks of 25,000 emails at $20/block (volume discounts down to ~$10/block above ~4M/month) — and only as an add-on to a paid Mailchimp Standard or Premium plan. No standalone purchase, no free transactional tier.
Last checked 2026-08-02 against Mandrill's public pricing.
No — Mailchimp Transactional is an add-on for Standard and Premium marketing plans only. MailBlastr is standalone with a free tier, so transactional email never requires a marketing-suite subscription.
Two 25k blocks ($40) plus your Mailchimp Standard/Premium subscription — the true monthly total is well above MailBlastr’s entry plan, which includes 50,000 emails and the marketing layer.
For most product teams, yes: REST API + SDKs for transactional, campaigns/audiences/segments/automations/A-B for marketing, one audience store and one event stream. Mailchimp’s deep marketing suite (advanced journeys, multivariate, integrations catalog) still goes further for marketing-led orgs.
MailBlastr plans include contacts (1,000 free, up to 250,000 on stock plans) — contact count picks your plan tier rather than multiplying a separate per-contact bill.
Export templates (Handlebars ports to MailBlastr merge tags), verify your domain, swap sends to POST /emails or an SDK, and re-point webhooks. If you also leave Mailchimp, import audiences via CSV or the contacts API.
