Email Setup
Adding Your Custom-Domain Mailbox to iPhone Mail Manually
iOS Mail's quick-setup list only knows Gmail, iCloud and a few others — a mailbox on your own domain needs the Other account option with your hostname, port and SSL settings entered by hand.

In short
To set up email on iPhone for a custom domain, open Settings > Mail > Accounts > Add Account > Other, then choose Add Mail Account and enter your name, full email address, password and a description. On the next screen, select IMAP and fill in the incoming and outgoing mail server hostnames (usually mail.yourdomain.com), your full email address as the username, and your mailbox password again for both servers.
IMAP is the right protocol for a phone since it keeps mail synced with the server rather than downloading and removing it, so the same inbox stays consistent across iPhone, webmail and a desktop client at once.
iOS Mail's Add Account screen shows a short list of recognizable names — iCloud, Google, Yahoo, Outlook — and then, easy to overlook, an option simply labeled Other. That's the door into manual setup, and it's exactly what a mailbox on your own domain (you@yourbusiness.com) needs, since iOS has no way to auto-discover settings for a domain it's never seen before.
The setup itself is a handful of fields rather than anything complicated: a server hostname, a port number, and a toggle for SSL, all of which your hosting panel's email section displays exactly as needed. The most common stumbling point isn't difficulty, it's typing the wrong hostname or leaving SSL off, both of which produce a vague 'cannot verify account' error rather than a clear one telling you what's wrong.
Step 1: Find Your Mail Server Hostnames First
Before touching the iPhone, log in to your hosting panel's email section and locate the incoming (IMAP) and outgoing (SMTP) server hostnames for your mailbox, along with the recommended ports. These are commonly mail.yourdomain.com for both, though some setups list them slightly differently, so copy them exactly rather than guessing based on a setup you remember from another domain.
Having these details on hand before starting the iPhone setup avoids the most common failure: typing a plausible-looking hostname that isn't actually the one your hosting account uses. A single wrong character in a server address produces the same generic error as a wrong password, which makes it worth double-checking against the panel rather than troubleshooting blind afterward.
Step 2: Add the Account as "Other" in iOS Mail
On the iPhone or iPad, go to Settings > Mail > Accounts > Add Account, scroll past the recognizable providers, and tap Other. Choose Add Mail Account, then fill in your name (how it appears to recipients), your full email address, your mailbox password, and a description (like "Work Email") used only to label the account inside the Mail app.
On the next screen, tap IMAP at the top rather than POP, since IMAP keeps the phone in sync with the server copy of every folder instead of downloading mail and potentially removing it from where a desktop client or webmail also expects to find it.
Step 3: Enter Incoming and Outgoing Server Details
Under Incoming Mail Server, enter the IMAP hostname from your hosting panel, then your full email address as the username and your mailbox password. Under Outgoing Mail Server, enter the SMTP hostname the same way, along with the same username and password, since most setups use one set of credentials for both directions of mail.
Tap Next and let iOS attempt to verify the account. If it fails immediately, the hostname or password is the most likely cause; if it hangs or times out, the port or SSL setting is more often the culprit, which the next step addresses directly.
Step 4: Confirm SSL and Port Settings Match Your Host
After the account is added, go back into Settings > Mail > Accounts, tap the new account, then tap the SMTP entry under Outgoing Mail Server and open the primary server. Confirm SSL is toggled on and that the port field matches what your hosting panel specifies — typically 993 for secure IMAP and 465 for secure SMTP, though some hosts also support 587 for outgoing mail with SSL or STARTTLS.
If mail sends but doesn't arrive, or arrives but won't send, this is almost always where the mismatch lives — one server's port or SSL toggle set correctly and the other left on an old default. Fixing whichever direction is failing, then sending a test email to yourself, confirms both sides are actually working rather than just one.
A Mailbox That Works the Same on Every Device

FAQ
Frequently asked questions
Why isn't my custom email showing up in iPhone Mail's quick setup list?
iOS Mail's quick list only auto-configures a handful of recognized providers like iCloud, Google and Outlook. A mailbox on your own domain needs the Other option under Add Account, where you enter the server hostnames manually.
Should I use IMAP or POP when adding email to my iPhone?
IMAP is almost always the right choice for a phone, since it keeps the inbox synced with the server rather than downloading and potentially removing messages. This keeps the same mailbox consistent across your phone, webmail and any desktop client.
What port should I use for IMAP and SMTP on iPhone?
993 is the typical secure port for incoming IMAP mail, and 465 (or sometimes 587 with STARTTLS) is typical for outgoing SMTP. Always confirm the exact port against your hosting panel's email settings rather than assuming these defaults apply universally.
My iPhone says it can't verify the account name or password — what's wrong?
This almost always means the hostname, username or password doesn't match what the mail server expects, most often a mistyped hostname or a password that's since been changed. Recheck the exact IMAP and SMTP hostnames in your hosting panel and re-enter the password carefully.
Why can I receive email on my iPhone but not send it?
This points to the outgoing (SMTP) server settings specifically, usually a wrong port or SSL toggle. Go to Settings > Mail > Accounts, tap the account, then the SMTP server, and confirm the port and SSL setting match what your hosting panel specifies.
Can I use the same email account on my iPhone and my computer at the same time?
Yes, as long as the account is set up as IMAP rather than POP on both, since IMAP keeps every device showing the same synced state of the mailbox. POP is designed around a single device downloading and often removing mail, which causes inconsistencies across multiple devices.
