My mass email limit has not been exceeded. Why am I still unable to send more emails in bulk?

You may be unable to send more emails in bulk if you're using a different Zoho CRM Edition. Your mass email count is calculated on a day-to-day basis, where 12 AM to 11.59 PM GMT is considered one day, based on your organization's time zone. The mass emails per day include Auto-responders, active Email SchedulersMacros and Mass emails.
You can increase your mass email limit to 2250 per day, per organization at an additional cost. Please write to us at sales@zohocorp.com to increase your mass email limit. Also, check out the Zoho Campaigns Integration with Zoho CRM. You can easily plan, execute campaigns and track the responses from contacts in CRM to make better sales decisions.
