How many emails per hour?

Sending too many emails per hour can get your messages flagged as spam. Here’s a guide to sending email responsibly while still reaching your targets.

How many emails per hour?

Email is an essential communication tool for personal and business use. However, sending emails irreponsibly can cause deliverability issues. Understanding optimal email sending limits helps ensure your messages reliably reach recipients.

This article outlines email best practices regarding sending cadence and volume. Follow these guidelines to keep your sender reputation strong, avoid landing in spam folders, and maximize email campaign performance.

Why email sending limits matter

Bulk email sending raises spam flags with Internet Service Providers (ISPs). Sending too many messages too fast suggests spam behavior rather than legitimate communication.

ISPs and email providers limit sends per hour to protect inboxes. Exceeding these limits causes deliverability issues:

  • Emails automatically filtered as spam
  • IP address blocked or blacklisted
  • Account suspended or terminated

Additionally, overly frequent email blasts frustrate recipients. Saturated inboxes lead subscribers to unsubscribe, report as spam, or ignore future emails.

Recommended sending frequency

So what’s the optimal number of emails to send per hour? Industry experts suggest:**

  • Individual accounts: Less than 100 emails per hour
  • Business accounts: Less than 2,000 emails per hour

These limits allow for effective communication without raising spam suspicions.

Tailor your approach based on factors like:

  • Account type: Individual or business
  • Email type: Transactional, promotional, etc.
  • List size: Small segment vs entire database
  • Engagement: Open/click rates

Track email metrics to refine your strategy over time.

Techniques for responsible sending

Abiding by email best practices protects your deliverability. Here are techniques to send efficiently:

1. Set sending limits

Configure send limits in your email service provider based on:

  • Account type
  • List size
  • Industry benchmarks

Test different caps to find the right volume for positive user experience.

2. Schedule campaigns

Strategically queue your messages to avoid hitting hourly limits.

Time email blasts during days/hours with high open rates. Use scheduling tools to easily set optimal send times.

3. Throttle sending speed

Slow the rate of blast sends for more gradual delivery. Send at half capacity to stay within constraints.

Many providers let you adjust sending velocity to fit needs.

4. Split campaigns

Divide large email campaigns into smaller segments. Send each segment in phases over multiple days or weeks.

Personalized, bite-sized blasts drive better results than saturating people all at once.

5. Monitor metrics

Pay close attention to the metrics for each campaign:

  • Send/delivery rates
  • Bounces
  • Opens/clicks
  • Unsubscribes
  • Spam reports

Refine your approach to balance effectiveness with responsible sending.

Key takeaways

  • Email providers enforce hourly send limits to prevent spam
  • Stay under 100 emails per hour for individual accounts
  • For business accounts, limit sends to 2,000 emails per hour
  • Schedule sends, throttle speed, and segment campaigns to respect limits
  • Monitor email metrics and user engagement to refine strategy

Sending emails excessively degrades deliverability, frustrates recipients, and damages sender reputation. Following responsible practices allows reaching more people without issues.

Conclusion

Tempting as it is to blast emails rapidly, restraint is vital for success. Abusing send limits hinders meaningful communication with real people. Invest time designing email campaigns for quality over quantity while respecting constraints. Your future self will thank you when your hard work pays off with engaged recipients and no blocked messages.

    Legally in the US under CAN-SPAM you must include opt-out options, sender addresses on marketing emails and not disguise subject lines. There are no email number limits, but excessive volume violates ISP terms and risks penalties for spam-like sending.
  10. What happens if you send over 300 emails a day in Gmail?
    Gmail alerts users approaching send limits. Over 300 emails per day risks throttled sending speed or spam filtering, although daily limits depend on account history & patterns. Consistently high sends hamper deliverability. Stick under 500 emails daily.

    Gmail personal accounts should limit sends to 100/hour, 500/day for best deliverability. Gmail caps emails at 2,000 per day to discourage spamming – exceeding that threshold risks send restrictions or spam box filtering even if legal.

    Yes, both your domain/IP and individual accounts can end up on an ISP or ESP’s blacklist for excessively high volumes that resemble spamming. This leads all your emails automatically being filtered as spam. Carefully follow recommended limits.

But just because it is legal does not mean it is advisable – sending 1000+ emails daily often harms deliverability due to spam risk.

    Gmail may throttle send speed for accounts sending over 500 emails per 24 hours as this activity resembles spammers. Sustained high volume risks automatic spam filtering or banned accounts. Spread out scheduling, keep under 500 daily, and monitor bounce/spam complaint rates.
  19. Can you get in trouble for sending too many emails from Gmail?

    The general limit for emails sent per day in Gmail consumer accounts is 500 per day to balance deliverability with spam risk. Google technically allows up to 2000 per day before throttling, but lower volumes ensure emails reliably reach inboxes rather than spam folders.
  22. Can I get banned for mass emailing?
    Yes, you can get banned by email providers and Internet Service Providers for excessively high email volume that qualifies as spamming or abusive behavior. Carefully follow recommended limits for mass emails and avoid repeatedly sending to unengaged people or those who unsubscribe.
