独自ドメインで使うビジネスメール

Owning you@yourdomain.com is only step one — inbox providers also check whether your domain is authorised to send mail before they trust it. SPF confirms which servers can send on your behalf, DKIM signs each message so it can't be tampered with in transit, and DMARC tells receiving servers what to do if a message fails those checks.

Without these DNS records in place, legitimate mail can land in a recipient's spam folder or get rejected outright, and it becomes far easier for someone to spoof your domain. Records are added through the same control panel used to manage mailboxes, and support can talk you through the exact values if you've never set them up before.

A catch-all address collects anything sent to a misspelled or guessed address at your domain instead of bouncing it — useful when customers type sales@ instead of sale@, or when an old contact address still gets the occasional message. It's configured once and needs no ongoing maintenance.

Autoresponders cover holiday and out-of-office replies without you touching each message individually, and forwarding rules let one address quietly fan out to several people — handy for a shared support@ or info@ mailbox a small team monitors together. All of this draws from the same pool of up to 500 aliases and forwarders included with the plan.

Daily backups apply to mailbox data as well as web files, and are stored apart from the live account — so an accidentally deleted folder, a bad filter rule, or a compromised password doesn't also destroy the copy you'd need to recover from. Open a support ticket and the team can help pull a folder back from a recent backup point.

Because email hosting carries the same 30-day money-back guarantee as our other plans, you can migrate a domain's mail across, run it for real for a few weeks, and confirm deliverability and mailbox limits work for your team before you're committed. 24/7 human support is there if anything about the setup looks off in that window.

If a domain's website already sits on one of our web hosting plans (from $2.42/mo), it already includes mailboxes at no extra charge, so a standalone email plan mainly suits domains that are parked, pointed elsewhere, or hosted with another provider entirely — agencies juggling several client domains often fall into exactly this case.

Pricing displays automatically in your local currency through geo-currency detection, while invoices are settled in USD by Bohzo Ltd, the UK-registered company behind Hosting Cheap. That billing stays consistent whether a domain stays on standalone email hosting or the site later moves up to managed WordPress (from $4.19/mo), a VPS (from $9.99/mo) or a dedicated server (from $149.99/mo).
