Sending Limits

Learn why email servers have daily and hourly sending limits, even in self-hosted setups. Understand how to optimize sending while maintaining high deliverability.

Why Is There a Daily or Per-Hour Sending Limit If It’s My Own Setup?

When setting up your own email server, you may wonder why sending limits exist even though you fully control the infrastructure. While there are no enforced restrictions from BulkEmailSetup, technical limitations, email provider policies, and best practices require a controlled approach to sending.

1. Why Are There Sending Limits?

Although a self-hosted email server gives you full control, several factors impact how many emails you can send per day or per hour:

1️⃣ Email Provider & ISP Policies

  • Major ISPs (Gmail, Outlook, Yahoo) monitor incoming email volume from IPs and domains.

  • Sending too many emails too fast can trigger spam filters, delaying or blocking emails.

  • Email reputation builds over time—new IPs and domains need gradual warm-up.

2️⃣ IP & Domain Reputation

  • ISPs score senders based on complaint rates, bounce rates, and engagement.

  • High-volume sending from a new or untrusted IP can lead to blacklisting.

  • Warm-up plans help establish a positive sender reputation.

3️⃣ Server Infrastructure & Resource Limitations

  • Email servers require CPU, RAM, and bandwidth to process high volumes.

  • Sending millions of emails at once may overwhelm your server, causing failures.

  • Proper queue management ensures steady email delivery without overload.

4️⃣ Spam Prevention & Compliance

  • GDPR, CAN-SPAM, and CASL require responsible email sending.

  • High complaint or bounce rates can result in ISP blocks and blacklist issues.

  • Controlled sending ensures better inbox placement and long-term deliverability.


2. How Are Sending Limits Determined?

Your sending limits depend on:

Factor

Impact on Sending Limit

Server Type

VPS or Dedicated Server affects processing power.

Number of IPs

More IPs allow better rotation and higher sending capacity.

Domain Age & Reputation

Older, trusted domains can send more emails.

IP Warm-up Progress

Gradually increasing sending volume prevents blacklisting.

Email List Quality

Verified contacts reduce bounce rates and improve reputation.


3. Recommended Daily & Hourly Sending Strategies

Setup Type

Recommended Daily Sending

Recommended Hourly Sending

New Setup (Fresh IPs & Domains)

1,000 – 2,000 emails/day

50 – 100 emails/hour

Warm-up Stage (First 2-4 Weeks)

5,000 – 20,000 emails/day

500 – 1,000 emails/hour

Established Server (Trusted IPs & Domains)

50,000+ emails/day

2,000+ emails/hour

🔹 Tip: Use IP and domain rotation to distribute sending across multiple resources for higher capacity.


4. How to Increase Your Sending Limits

If you want to send more emails without triggering blocks or affecting deliverability:

✅ Gradually Increase Volume – Start small and build trust with ISPs. ✅ Use Multiple IPs & Domains – Rotating sender details helps avoid spam filters. ✅ Authenticate Your Emails – Set up SPF, DKIM, and DMARC for better trust. ✅ Monitor Deliverability – Track open rates, bounces, and complaints regularly. ✅ Warm Up New IPs Properly – Follow structured warm-up plans before full-scale sending.


5. Conclusion – Send More While Maintaining Deliverability

While a self-hosted email server gives you control, email providers enforce best practices to prevent spam, protect users, and maintain high inbox placement. Following structured sending strategies will ensure your emails reach inboxes without being blocked.
