Setting up SimpleEmail is fairly simple. You'll need to add at least one account to receive email and at least one identity if you want to send email.
An internet connection is required to add accounts and identities.
Your email provider should support secure connections. If your provider doesn't support secure connections and you care at least a little about your privacy, you are strongly advised to switch to another provider.
For security reasons, your account need to have a non empty password set.
To add an account, tap on Manage accounts and tap on the orange add button at the bottom. Select a provider from the list, enter the username, which is mostly your email address and enter your password. If you use Gmail, tap Select account to fill in the username and password. Tap Check to let SimpleEmail connect to the email server and fetch a list of system folders. After reviewing the system folder selection you can add the account by tapping Save.
If your provider is not in the list of providers, select Custom. Enter the domain name, for example gmail.com and tap Get settings. If your provider supports auto-discovery, SimpleEmail will fill in the host name and port number, else check the setup instructions of your provider for the right IMAP host name and port number.
Similarly, to add an identity, tap on Manage identity and tap on the orange add button at the bottom. Enter the name you want to appear in de from address of the emails you send and select a linked account. Tap Save to add the identity.
See this FAQ about using aliases.
If you want to lookup email addresses, have contact photos shown, etc, you'll need to grant read contacts permission to SimpleEmail. Just tap Grant permissions and select Allow.
On recent Android versions, Android will put apps to sleep when the screen is off for some time to reduce battery usage. If you want to receive new emails without delays, you should disable battery optimizations for SimpleEmail. Tap Disable battery optimizations and follow the instructions.
