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 GMX Mail accounts.
What are GMX Mail's SMTP settings?
GMX Mail's outgoing (SMTP) server is mail.gmx.com. Use port 587 (STARTTLS) or 465 (SSL/TLS). SSL/TLS on 465 (recommended) or STARTTLS on 587. Sign in with your full email address and password (or app password).
What is GMX Mail's IMAP or POP3 server?
GMX Mail's incoming IMAP server is imap.gmx.com on port 993 (SSL/TLS). If you prefer POP3, use pop.gmx.com on port 995.
Which port should I use for GMX Mail?
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. GMX Mail's recommended value is above.
Why won't my GMX Mail SMTP connection work?
Check authentication first: Turn on POP3/IMAP access under Settings before connecting — it is disabled by default. GMX uses your normal password once POP3/IMAP is enabled; no separate app password is required. 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 GMX Mail?
Not at scale. Varies by account age and status. 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.
