If you’re looking to set up email on your iPhone SE, there are a few different ways to go about it. You can use the built-in Mail app, or you can use an external email app like Gmail or Outlook. Whichever route you choose, here’s how to set it up. To use the built-in Mail app, open it and tap the “Mail” icon at the bottom. On the main screen, scroll down and tap “Settings.” Under “Mail,” tap “Accounts.” Tap “Add Account.” Enter your email address and password (if necessary), and then tap “Next.” Under “Server,” select your mail server (Gmail, Outlook.com, etc.), and then enter your port number if necessary. Tap “Next.” Under “Configure Email,” make sure that both the box next to “Send Email From” and the box next to “Use Incoming Email Server” are checked. If you want to send attachments with your emails, check the box next to “Send Attachments With Emails.” Tap “Save Changes.” If you want to use an external email app like Gmail or Outlook instead of using the built-in Mail app, first make sure that those apps are installed on your iPhone SE. Next open those apps and sign in with your account information. On the main screen of either app, scroll down and tap Settings. Under Settings for Gmail or Outlook respectively, tap Accounts. Tap Add Account and enter your email address and password (if necessary). Next under Server type in either Gmail or Outlook’s server name (for example: outlook.office365.com) followed by their port number if necessary (port 25 for Gmail; port 587 for Outlook). Finally under Configure Email make sure both boxes next to Send Email From & Use Incoming Email Server are checked before saving changes ..
