Front’s sequences allow you to automate outreach and communications to a group of people.
Currently, Front allows you to send a single sequence to up to 200 recipients.
Because you can send numerous sequences per day, we want to strongly advise you to not over-send. Each provider (Gmail, Office 365, etc) has sending limits, so the amount that you’ll be able to send will depend on your provider. If you start to see failure notices, it’s most likely due to your provider’s sending limit. Unfortunately, Front can't guarantee that everything will be sent properly in these cases. We do have a mechanism for retrying a sequence if it fails, but some limits are strict and do not allow us to move further.
If you want to send a larger volume, it's highly recommended that you set up a custom SMTP inbox to send from.
This will not result in a raised recipient limit for a single sequence, however it may allow you to successfully send multiple sequences in parallel, which is not possible with providers such as Gmail and Office 365 due to their sending limits.
You can re-use sequences, so if you do hit your max halfway through sending, wait 24 hours and restart the sequence.
Remember that these sending limits are also true for regular emails. If you reach your limit with sequences, you will also be blocked from replying to emails that come in to the inbox that has reached the limit.
