"Mautic: Open Source Marketing Automation Software."

Self-host vs Mailchimp

Example values: replace every number with your own. None of them is vendor data.

Self-hosting saves about $780 a year for 20 seats: SaaS $2,400 vs self-host $1,620 (server $144, backups $36, admin time $1,440). Break-even at about 14 seats at these numbers.

Admin hours start from our guess for difficulty unrated and are yours to edit. Mailchimp price: $13 a month flat (Essentials plan). No per-seat price. Per-contact, no per-seat price: Essentials from $13/mo (500 contacts); Standard $20/mo; Premium $350/mo (10,000 contacts). Corroborated; the vendor page did not render prices as text.
