Run these yourself
What each one actually needs — real RAM, honest running cost, and the setup time nobody quotes.
- Self-hosting listmonk 1 GB
- Self-hosting Keila 1–2 GB for Keila and PostgreSQL together. This is an estimate from the 512 MB app limit Cloudron uses plus a small database; Keila publishes no sizing of its own.
- Self-hosting Mautic 4 GB for a list in the low tens of thousands, 8 GB beyond that. One 4 GB server ran out of memory updating segments at about 50,000 contacts on Mautic 5.
- Self-hosting phpList 1–2 GB on a VPS for phpList with MySQL. A long-time phpList forum helper called a 2 GB VPS fine for slower sending, with more RAM needed as the database grows.
