Free WordPress email tools: SPF, DKIM, DMARC, and more.
The WordPress Email Authority
Forwarding routes mail sent to an address on a domain you own to a mailbox you actually read — the inbound half of running email under your own domain. What separates the services below is whether they rewrite the SPF envelope so forwarded mail still authenticates at Gmail, and whether they also send as the domain or leave outbound to a separate SMTP provider. The roundup underneath walks the picks and the two decisions — Cloudflare or not, and send or receive-only — that steer the choice.
One roundup, eight services, picks by need — Cloudflare-hosted, off-Cloudflare, cheapest with SMTP sending, real mailbox on the domain.
The best email forwarding service for a WordPress site depends on whether you need to send from the domain, not just receive. Eight services compared.

addy.io (formerly AnonAddy) is an independent, open-source email aliasing service. Unlimited standard aliases on custom domains from $3/month on the Pro tier.

Cloudflare Email Routing forwards inbound mail for free on any domain on Cloudflare DNS, with the same authentication stack (SRS, ARC, DKIM) as paid services.

EmailForwardMX is a forwarding service owned by ForwardMX Limited, the same company behind ForwardMX. Similar features and pricing. See ForwardMX for the full review.

Fastmail is a full email host with custom domain support, Masked Email aliases, and JMAP API. Overkill for forwarding alone; the right choice if you need mailboxes.

Forward Email offers unlimited free forwarding and $3/month encrypted mailbox hosting. Source-available codebase. Generous free tier; modest sending limits.

ForwardMX is a UK-based forwarding service with SMTP sending and optional mailboxes. No free tier. The agency-friendly option for managing many domains.

Google Domains was a domain registrar with free email forwarding. It was sold to Squarespace in September 2023. Forwarding continues under Squarespace Domains.

ImprovMX forwards email for custom domains with a usable free tier and paid SMTP sending. The right choice for simple forwarding; not a mailbox replacement.

Mailbox.org is a Berlin-based email host with custom-domain mailboxes, catch-all forwarding, server-side PGP, and BSI C5 attestation. The EU-jurisdiction alternative to Fastmail from €3/month annual; overkill for forwarding alone.

Mailwip (formerly Hanami) is an independent email forwarding service with SMTP sending, webhooks, and IMAP access on higher tiers. Small operator; low entry price.

Migadu is a flat-rate Swiss email host: unlimited addresses across unlimited custom domains at every paid tier. Priced for operators past per-seat mailboxes.

Namecheap includes free email forwarding with every domain registration. 100 aliases, catch-all, no SMTP sending. The zero-cost default for Namecheap customers.

Pobox was one of the oldest email forwarding services (founded 1995). It was acquired by Fastmail in 2015 and fully merged in November 2024. No longer available.

Porkbun bundles free email forwarding with every domain, 20 aliases per domain, and, unlike Namecheap, it works whether the domain is registered at Porkbun or somewhere else. Receive-only; no SMTP send, no catch-all.

SimpleLogin is a privacy-first email aliasing service owned by Proton. Unlimited aliases and custom domains on the $4/month Premium tier. Fully open-source and self-hostable.
