• Incoming Mail Server: imap.ionos.com
• Port: 993
• Security: SSL / TLS
• Username: Your full email address
• Password: Your email password

5. Enter Outgoing Mail (SMTP) Settings

• Outgoing Mail Server: smtp.ionos.com
• Port: 587
• Security: STARTTLS
• Username: Your full email address

7. Final Settings (Recommended)
After setup, open the account settings inside Spark and confirm:

• Push Notifications are enabled
• Signature is updated (remove default Spark branding if needed)

Troubleshooting Tips

• Make sure your password is correct — failed logins are usually authentication-related.
• Always use your full email address as the username.
• Do not use POP3 — IMAP keeps devices synced.
• If setup fails, double-check ports and SSL settings exactly as listed above.

Troubleshooting Tips

• Use your full email address as the username (not just the name before @).

• Make sure SMTP is using 587 + STARTTLS (not 25).
• Do not use POP3 — IMAP is required for sync across devices.
