The constraints imposed on the number of emails that can be sent from HubSpot within a 24-hour period is a critical aspect of the platform’s email sending functionality. For example, a Marketing Hub Professional account might have a specific quantity of emails allowed per month, but also an additional cap on the number that can be initiated on any given day to avoid exceeding the monthly limits and to maintain optimal deliverability.
Understanding and managing this restriction is vital for maintaining consistent and effective email marketing campaigns. This constraint helps ensure responsible email practices, prevents abuse, and ultimately contributes to better sender reputation with ISPs. Historically, such limitations have been implemented across various email platforms as a mechanism to combat spam and bulk email practices that negatively impact the overall ecosystem of electronic communication.
