Consumer limits
Gmail caps at 2,000 emails/day. Yahoo around 2,400/day. Bulk campaigns need a professional SMTP relay with monthly volume tiers, not daily caps.
What is my SMTP server?
The first question when configuring an email client: which SMTP hostname should you use? Free consumer servers are not built for bulk sending — use a dedicated relay like SMTPServer for campaigns and transactional mail at scale.
Popular provider SMTP hostnames
Use these outgoing server names in your email client. For bulk or app sending, switch to SMTPServer SMTP relay — dedicated IPs from €39/month for 100,000 emails.

Why use SMTPServer instead of Gmail SMTP?
Dedicated reputation
Every paid SMTPServer plan includes a dedicated IP so your sender reputation is isolated from other senders.
Where are my SMTPServer credentials?
After signup and domain verification, open Dashboard → SMTP settings for hostname, port, username, and password. See installation steps.
Test before sending
