Setting up email in a client, script or app means knowing the exact SMTP, IMAP and POP3 server details for your provider — the hostname, the port, and whether to use STARTTLS or SSL/TLS. Get one wrong and the connection silently fails.
This free finder keeps the current, public settings for the providers people configure most — Gmail, Outlook.com, Microsoft 365, Yahoo, iCloud, Zoho and more — with a copy button on every field so you can paste them straight in.
SMTP is the outgoing server that sends your mail. IMAP and POP3 are the incoming servers that fetch it: IMAP syncs across all your devices and is the modern default, while POP3 downloads to a single device. For most setups you'll enter SMTP for sending and IMAP for receiving.
Whatever you're wiring up, remember the send limits: consumer mailboxes cap out at a few hundred emails a day. For cold outreach at volume, Emailchaser handles inboxes, warmup and deliverability so you don't burn a single account.
What are SMTP settings?
SMTP (Simple Mail Transfer Protocol) settings are the details your email client or app needs to send mail through a provider: the outgoing server hostname (for example smtp.gmail.com), a port (usually 587 or 465), and a security method (STARTTLS or SSL/TLS), plus your username and password. Enter or pick a provider above to see its exact values.
What is the difference between SMTP, IMAP and POP3?
SMTP sends email out. IMAP and POP3 bring email in. IMAP keeps your mail on the server and syncs it across every device, so it's the modern default. POP3 downloads messages to one device and (by default) removes them from the server. You'll usually configure SMTP for sending plus IMAP for receiving.
What SMTP port should I use — 587, 465 or 25?
Use port 587 with STARTTLS wherever possible — it's the modern standard for authenticated submission. Port 465 with SSL/TLS is a widely supported alternative. Avoid port 25: it's meant for server-to-server relay and is blocked by most home and cloud networks for client sending.
Why is my SMTP connection not working?
The most common cause is authentication. Providers like Gmail, Yahoo, iCloud and Fastmail block your normal password over SMTP and require an app password with two-factor authentication enabled. Microsoft 365 often needs an admin to switch on SMTP AUTH. Double-check the host, port and security method too — a 587/SSL or 465/STARTTLS mismatch will fail.
Can I send bulk or cold email over SMTP?
Not at scale. Every mailbox provider caps daily sends (roughly 300–500 a day for consumer accounts, ~2,000 for Google Workspace) and throttles bursts to prevent spam. Sending cold email through a single SMTP mailbox will hit limits and hurt deliverability fast. High-volume outreach belongs on dedicated infrastructure that spreads sending across warmed inboxes — which is what Emailchaser does.
