When using your hosting account for email communication, you'll encounter email sending limits. These are restrictions set by hosting providers on the number of emails you can send per hour or per day from your account. They are a crucial part of maintaining server health and preventing abuse.

These limits exist primarily for security and performance reasons. They help prevent spam from being sent through compromised accounts, which protects the hosting provider's IP reputation. A good reputation ensures emails from all customers on the server reach recipients' inboxes instead of being marked as spam. Limits also prevent a single account from overloading the server's mail system, ensuring stable performance for everyone.

Typical limits you might see include:

• Per-hour limits: Often range from 100 to 500 emails.
• Per-day limits: Can range from 1,000 to several thousand emails.

These numbers vary significantly between shared hosting, VPS, and dedicated server plans.

What happens if you exceed the limit? Your outgoing emails will typically be temporarily blocked until the next time period begins (e.g., the next hour). You will usually receive a notification or bounce-back message. For legitimate bulk email needs, such as newsletters, you must use a dedicated email marketing service (like Mailchimp or Sendinblue) that is designed for high-volume sending and maintains proper sender authentication.

To check your specific limits, consult your hosting provider's knowledge base or terms of service, or contact their support team. Staying within these limits is essential for reliable email delivery and maintaining a healthy hosting environment.
