There are a number of benefits to email throttling, including:

-Increased deliverability: By sending fewer emails, you are less likely to be labeled as a spammer. This can improve your sender reputation and increase the likelihood that your messages will reach the inbox.

-Improved sender reputation: A good sender reputation is essential for getting your emails delivered to the inbox. Throttling your emails can help improve your sender reputation, making it easier for your messages to reach their intended destination.

Email throttling can be an effective way to improve sales and deliverability.

1. Per-domain throttling limits the number of emails that can be sent from a single domain in a given period of time. This is often used to prevent spammers from using multiple domains to send large volumes of email.

2. Per-recipient throttling limits the number of emails that can be sent to a single recipient in a given period of time. This is often used to prevent one sender from overwhelming a recipient's inbox with too many messages.

3. Per-message throttling limits the number of messages that can be sent in a given period of time. This is often used to protect email servers from being overloaded by too many messages.

If you email infrequently or have a large list of contacts, you may notice that your campaign sends are throttled. This means that your messages will be sent out over a period of time rather than all at once. This is done to protect our email sending reputation and to ensure that your messages reach the inboxes of your contacts. If you need to send email more quickly, you can try increasing your email sending frequency or splitting up your list into smaller groups.

The answer to this question depends on a number of factors, such as the nature of your business, the type of email campaigns you send, and your goals for each campaign. However, as a general guideline, it's generally advisable to email your subscribers at least once per month. This frequency will help keep your brand top-of-mind, without bombarding your subscribers with too many emails. Of course, if you have important news or announcements that need to go out more frequently, you can always adjust your email cadence accordingly.
