Keep Your Email Hosting Separate From Your Website Host

Most cheap hosting plans include email, and it is tempting because it is free and already there. It also ties the most business-critical system you own, your email, to the least important decision you make, where your marketing site is hosted.

Why separating them is worth the small cost

• Independence during outages. If the web server goes down, you can still communicate with customers. Combined, one failure takes both.
• Deliverability. Shared hosting IPs are shared with other people's mail. One spammer on the same server and your legitimate invoices land in junk folders. Dedicated providers manage reputation as their core business.
• Migration freedom. Changing web hosts becomes a routine task instead of an email cutover with hours of risk. This alone traps businesses on hosts they have outgrown.
• Features and reliability. Storage, search, spam filtering, mobile sync, and shared calendars from a dedicated provider are in a different category from a bundled mailbox.
• Security. A compromised website should not put your inbox in the same blast radius. Email is where password resets go, which makes it the master key to everything else.

How to make the move

1. Choose a provider and create the accounts before changing anything.
2. Migrate existing mail with the provider's import tool, which will copy folders and history.
3. Update MX records, and update SPF, DKIM, and DMARC at the same time. Getting these right is what keeps your mail out of spam folders.
4. Leave the old mailboxes in place for a couple of weeks to catch stragglers.
5. Update anything that sends mail from your domain: the website's contact form, invoicing software, booking systems, and newsletters.

The website part people forget

Forms and receipts sent from your web server are a common source of deliverability problems. Configure the site to send through an authenticated mail service rather than the server's default, and your notifications stop landing in junk. That change alone recovers leads on a surprising number of sites.

The cost

A few dollars per mailbox per month. Set against a day of email downtime or a month of invoices going to spam, it is not a close call.
