Best VPS for an Email Server

Self-hosting email is mostly about deliverability, not horsepower. The VPS is the easy part — the hard part is a clean sending reputation.

What an email server needs

• A dedicated IPv4 with reverse DNS (PTR) you control.
• Full root to install Postfix, Dovecot, and DNS records.
• 1–2 GB RAM for a small mail setup (Mailcow wants 2 GB minimum).

The pick: RackNerd 2GB

RackNerd’s 2 GB plan at $35.99/yr runs Mailcow or a Postfix plus Dovecot stack, with full root and a dedicated IPv4. Budget the 4 GB plan at $59.99/yr if you want spam filtering (rspamd) with headroom.

The deliverability checklist

• Set SPF, DKIM, and DMARC — without them, most mail lands in spam.
• Configure PTR records to match your hostname.
• Warm up the IP — start with low volume, then scale.
• Keep port 25 outbound clean — never send bulk mail from a cold IP.

Bottom line: 2 GB is plenty for the software; your sending reputation is what actually determines whether it works.
