What Are Email Rate Limits?
Updated over 3 months ago

Referral Factory has rate limits on how many daily emails you can send for your referral program. This guide covers how email rate limits work, the limits for each plan, and how to increase your limit.


What Are The Email Rate Limits for Each Plan

Referral Factory has rate limits on how many emails you can send per day, these rate limits apply to all plans. The allocated number of emails you can send per day will depend on your plan.

Starter = 100 emails per day

Basic = 2000 emails per day

Pro = 3000 emails per day

Enterprise = Unlimited emails per day

If you decide to send a once-off email or any other emails that surpass your rate limits, Referral Factory will send you a notification beforehand. This notification is to inform you that some or all of your emails will not be sent.


Which Emails Count Towards The Email Rate Limit?

Every email that is sent via Referral Factory counts toward your daily total. For example, if you set up a once-off email and send it to 500 contacts, that is calculated as 500 emails sent.

Your email send limit will reset each day. So, if you reach your daily email rate limit, you will have to wait 24 hours in order to send more emails.

The following types of emails count toward your send limit:

Once-off emails to your audiences

Email notifications for the person referring

Email notifications for the person invited

Reminder emails for both the person referring and the person invited

→ Test emails you send while setting up your campaign

How To Increase or Bypass Your Email Rate Limit

If you would like to increase your rate limits so that the email sending for your campaign is not interrupted, you have the following options:


1. Upgrade Your Plan

Depending on how many emails you plan to send per day, you could upgrade your subscription to a higher plan in order to lift your daily rate limits. Read this article to see how to upgrade your subscription or visit the pricing page.

2. Purchase Additional Emails

Another option is to purchase more emails to increase your rate limits. You can purchase emails in intervals of 10,000 at a cost of $0.005 per mail. So if you wanted to purchase 10,000 emails, that would cost $50.00.

To purchase additional emails...

→ Navigate to the Settings tab of your Referral Factory dashboard.

→ Click on Emails and Domains.

→ Scroll down until you see Email Rate Limits.


→ Select the number of additional emails you would like to purchase.

→ Click Add.

→ A pop-up will appear with a link to an invoice. This invoice will also be emailed to you.

3. Add Your Own Mail Server (Available on All Plans)

You can still use Referral Factory to trigger and send email notifications for your referral program but, instead of sending those emails through our mail server, which will have a rate limit, you can choose to send them through your own mail server. This feature is available on all Referral Factory plans.

❗️ If you enable your own mail server, Referral Factory won't be responsible for ensuring deliverability, you will have to ensure this through your own mail provider.
