Front integrates with different types of channels, which have varying numbers of total recipients you can send to, depending on the nature of the channel.
Recipient limits are:
100 recipients for email forwarding channels (Google Groups, Distribution Lists, Exchange On-Prem, SMTP Forwarding, etc.)
100 recipients for Gmail channels. See Google's article here for more information.
500 recipients for Office 365* channels
1 recipient for WhatsApp, TwitterDM, Front Chat, Intercom, Sunshine Conversations (formerly Smooch)
200 recipients for SMS
100 recipients for custom channels
*Office 365 supports a scalable recipient limit from 1-1000 which is configurable in the Exchange Admin Center (see here). If you have a discrepancy between the configuration in your systems and Front's recipient limit, please contact us to see if the limit can be increased.
In cases where you’d like to send to a number of recipients above the limits of your channel, you have several options:
Send the email to a distribution list where hundreds of recipients can receive your message
Split your recipient list into smaller groups and send a separate message per group
If you are often mass sending marketing or promotional messages, we recommend checking out mail merge platforms that specialize in mass outbound marketing messaging
