How many mails can send at time

The number of emails that can be sent at one time depends on several factors, including:

1. Email service provider: Different email service providers (ESPs) have different limits on the number of emails that can be sent at one time. For example:
   • Gmail: 500 emails per day (with a maximum of 100 emails per hour)
   • Outlook: 300 emails per day (with a maximum of 100 emails per hour)
   • Mailchimp: 10,000 emails per day (with a maximum of 1,000 emails per hour)
2. Email client: The email client you use to send emails can also have limits on the number of emails that can be sent at one time. For example:
   • Microsoft Outlook: 100 emails per hour
   • Mozilla Thunderbird: 100 emails per hour
3. ISP (Internet Service Provider): Your ISP may also have limits on the number of emails that can be sent at one time. For example:
   • Comcast: 500 emails per day
   • AT&T: 500 emails per day
4. Email campaign: If you're sending a large email campaign, you may need to consider the limits imposed by your ESP or email client. For example:
   • Mailchimp: 10,000 emails per day (with a maximum of 1,000 emails per hour)
   • Constant Contact: 10,000 emails per day (with a maximum of 1,000 emails per hour)

In general, it's recommended to send emails in batches, rather than all at once, to avoid overwhelming your ESP, email client, or ISP. This can help prevent your emails from being flagged as spam or blocked.

Here are some general guidelines to keep in mind:

• For small email campaigns (less than 100 emails), you can usually send them all at once.
• For medium-sized email campaigns (100-1,000 emails), consider sending them in batches of 100-200 emails at a time.
• For large email campaigns (1,000-10,000 emails), consider sending them in batches of 500-1,000 emails at a time.
• For very large email campaigns (more than 10,000 emails), consider using a dedicated email service provider or consulting with an email marketing expert.

Remember to always check with your ESP, email client, or ISP to determine their specific limits and guidelines for sending emails.
