Sending limits & login
Daily send limit
Follows Microsoft 365 limits — up to 10,000 recipients per day.
Authentication
SMTP AUTH must be enabled on the mailbox. Because this is Microsoft 365, Basic Auth for IMAP/POP is disabled on most tenants, so those protocols may require OAuth/modern auth rather than an app password.
App password
Manage security and app passwords via your Microsoft 365 account settings.
Newer GoDaddy Professional Email is Microsoft 365-based (settings above). Legacy GoDaddy Workspace Email used smtpout.secureserver.net (465) with pop/imap.secureserver.net.

Those caps make single-mailbox sending fine for personal mail but a poor fit for cold outreach at volume. Emailchaser spreads sending across warmed inboxes and manages deliverability, so you can scale without burning GoDaddy accounts.
What are GoDaddy's SMTP settings?
GoDaddy's outgoing (SMTP) server is smtp.office365.com. Use port 587 (STARTTLS). STARTTLS on 587. GoDaddy Professional Email runs on Microsoft 365. Sign in with your full email address and password (or app password).
What is GoDaddy's IMAP or POP3 server?
GoDaddy's incoming IMAP server is outlook.office365.com on port 993 (SSL/TLS). If you prefer POP3, use outlook.office365.com on port 995.
Which port should I use for GoDaddy?
Use port 587 with STARTTLS wherever it's offered — it's the modern standard for authenticated sending. Port 465 with SSL/TLS is a solid alternative. Avoid port 25, which most networks block for client sending. GoDaddy's recommended value is above.
Why won't my GoDaddy SMTP connection work?
Check authentication first: SMTP AUTH must be enabled on the mailbox. Because this is Microsoft 365, Basic Auth for IMAP/POP is disabled on most tenants, so those protocols may require OAuth/modern auth rather than an app password. Manage security and app passwords via your Microsoft 365 account settings. Then confirm the host, port and security method match exactly — a 587/SSL or 465/STARTTLS mismatch will fail to connect.
Can I send bulk or cold email through GoDaddy?
Not at scale. Follows Microsoft 365 limits — up to 10,000 recipients per day. Providers throttle bursts to fight spam, so pushing cold email through one mailbox hits limits and wrecks deliverability. High-volume outreach belongs on dedicated infrastructure that spreads sending across warmed inboxes — which is what Emailchaser does.
