Add Business Email to iPhone and Apple Mail

Most founders read and reply to work mail from a phone first. On iPhone, that usually means the built-in Mail app (or Mail on a Mac). You can connect a MailShrine address with IMAP for sync and SMTP for send — without moving to iCloud-only mail or Google Workspace.

Copy hosts and ports from MailShrine before you tap anything (IMAP & SMTP settings). Never type hostnames from memory or random TikTok overlays.

Real-life example: Lekki Ceramics

Tomi runs Lekki Ceramics, a home-studio pottery brand. Orders come to hello@lekkiceramics.ng (alias on her mailbox). She needs the alias mailbox on her iPhone while glazing — laptop stays at the studio.

What success looks like:

1. Account added via Other → IMAP (not Google or Exchange).
2. New Instagram inquiry lands on the phone within a minute of webmail.
3. Replies show her professional From address.

What to copy from MailShrine

Have these on a notes app or second screen:

Placeholders while you fill iOS fields:

• IMAP host: [copy from MailShrine]
• SMTP host: [copy from MailShrine]

Common ports are 993 (IMAP SSL) and 587 (SMTP STARTTLS) — only use them if they match what MailShrine shows.

iPhone: add the account (iOS Mail)

1. Open Settings → Mail → Accounts (on some versions: Settings → Apps → Mail → Mail Accounts).
2. Tap Add Account.
3. Choose Other (not Google, Microsoft Exchange, Yahoo, or iCloud).
4. Tap Add Mail Account.
5. Enter Name, Email, Password, and a Description (e.g. “Lekki Ceramics”).
6. Tap Next. When iOS fails to auto-detect, stay on IMAP (not POP).
7. Under Incoming Mail Server, paste MailShrine’s IMAP host; username = full email; password = mailbox password.
8. Under Outgoing Mail Server, paste MailShrine’s SMTP host; username/password again (required).
9. Tap Next / Save. Turn on Mail for the account.

If iOS asks for port details

1. Open the new account → Account → Advanced (incoming) and SMTP (outgoing).
2. Set incoming port + SSL to match MailShrine.
3. Under primary SMTP server, set outgoing port + encryption to match MailShrine.
4. Ensure Authentication is Password for SMTP.

Mac: Apple Mail

1. Open Mail → Settings (or Preferences) → Accounts → +.
2. Choose Other Mail Account… → Continue.
3. Enter name, full address, password → Sign In.
4. When prompted, choose IMAP and paste MailShrine incoming + outgoing hosts.
5. Finish. In Server Settings, double-check ports and SSL against MailShrine if send fails.

Same mailbox can sit on iPhone and Mac — that is the point of IMAP.

Proof it works

Tomi’s checklist

• Chose Other → IMAP (not Exchange)Completed
• Pasted IMAP + SMTP hosts from MailShrineCompleted
• SMTP username/password filled (not blank)Completed
• Round-trip send/receive succeededCompleted
• Signature updated for wholesale clientsNot completed

Common iPhone mistakes

1. Picking Exchange / Microsoft 365 — expects Microsoft tenants, not MailShrine IMAP.
2. Leaving SMTP username empty — iOS allows it; send then fails later.
3. POP instead of IMAP — mail downloads oddly; folders will not sync with webmail.
4. Guessing hosts — SSL name mismatch. Always re-copy from MailShrine.
5. Domain not verified — client setup cannot fix missing MX (setup guide).

Notifications and battery tips

• Allow Mail notifications for the business account only if you need interrupt-driven replies.
• Fetch vs Push depends on iOS and provider support; if mail feels slow, open Fetch New Data and try a shorter fetch interval for that account.
• Prefer Wi-Fi for the first large IMAP sync on an old inbox.
