Newton has built-in server settings for Yahoo, AOL, Fastmail, Zoho and GMX, so you only enter your email address and password. Yahoo, AOL and Fastmail need an app password instead of your normal password.
Click your avatar in the top-right corner and choose Add Account.
For Yahoo, choose Yahoo!. For AOL, Fastmail, Zoho or GMX, choose IMAP (other), then pick your provider from the Provider menu.
Enter your Email address and Password. Use the app password for Yahoo, AOL and Fastmail.
Click Test connection. When it says Connected, click Connect.

Setting up Newton for the first time? Only Yahoo has its own tile. For the others, tap IMAP and type the incoming server from the table below. Newton fills in the outgoing server for you.
Good to know
These are the settings Newton fills in, in case you need to check them:
Provider
Incoming (IMAP)
Outgoing (SMTP)
Yahoo
imap.mail.yahoo.com · 993 · SSL/TLS
smtp.mail.yahoo.com · 465 · SSL/TLS
AOL
imap.aol.com · 993 · SSL/TLS
smtp.aol.com · 465 · SSL/TLS
Fastmail
imap.fastmail.com · 993 · SSL/TLS
smtp.fastmail.com · 465 · SSL/TLS
Zoho
imap.zoho.com · 993 · SSL/TLS
smtp.zoho.com · 465 · SSL/TLS
GMX
imap.gmx.net · 993 · SSL/TLS
mail.gmx.net · 587 · STARTTLS
If you use two-factor authentication with Zoho, Zoho may ask for an application-specific password instead of your normal one.
Newton stores the password encrypted on its servers, so your other devices can connect without asking for it again.
In the mobile app, the Free plan includes two accounts. Adding a third there needs Newton Pro.
