SMTP and IMAP settings for every email provider
The exact server addresses, ports, and authentication requirements to connect any inbox or sending service, with the deliverability context that generic settings pages leave out. Pick your provider below.
Mailbox provider
Personal and webmail inboxes.
Business email
Custom-domain and hosted business mailboxes.
SMTP relay
Bulk and transactional sending services.
Correct settings get you connected. They do not get you delivered.
The right SMTP host and port let you send. Whether those emails reach the inbox depends on domain authentication, sender reputation, and warmup. Scheduler Zero warms your domains and manages sending so your cold email actually lands.
