What It Is
IMAP stands for Internet Message Access Protocol. It is one of the two main ways an email app reads your messages. With IMAP, the mail stays on the server and your devices show a live view of it. Read a message on your phone, and it shows as read on your laptop too. It is like a shared notebook in the cloud that everyone looks at, rather than separate copies.
Why It Matters for Your Business
Most small business owners check email on more than one device, often a phone during the day and a computer at night. IMAP keeps everything consistent, including folders and sent mail. If your laptop is stolen or breaks, your email is still safe on the server. For a team sharing one inbox, such as info@, IMAP lets everyone see which messages have been handled.
Good to Know
Because IMAP keeps everything on the server, it uses your mailbox storage. If your provider has a small limit, old messages with big attachments can fill it up. Archive or delete what you do not need. When setting up a new email app, choose IMAP over POP3 unless you have a specific reason, and have your incoming server settings from your provider ready.
