How to Add an Email to a Flow
To add an email to a flow, click on the Flows tab, and then on the name of the flow from the list. Below the list of existing flow emails is a button that reads Add Email to Flow.
The timing of a flow email can be set in hours or days. To send a flow immediately after the flow trigger, set the timing to 0 hours. When a flow email's delay is set in hours, it will be sent after the exact number of hours specified. The number of hours can be specified in tenths of an hour (e.g. 6 minute increments). For example, 0.5 hours will send an email 30 minutes after the flow trigger.
When a flow email's delay is set in days, you also specify a time of day and a timezone. When you specify a number of days, recipients will always wait at least the number of days you specify.
A few example flow email timings:
- 0 hours
If someone triggers this flows on Jan 1 at 12pm EST, an email will be sent immediately.
- 0.5 hours
If someone triggers this flows on Jan 1 at 12pm EST, an email will be sent on Jan 1 at 12:30pm EST.
The 0 before the decimal point is required.
- 48 hours
If someone triggers this flows on Jan 1 at 12pm EST, an email will be sent on Jan 3 at 12pm EST.
- 2 days at 3pm EST
If someone triggers this flows on Jan 1 at 12pm EST, an email will be sent on Jan 3 at 3pm EST.
- 2 days at 9am EST
If someone triggers this flows on Jan 1 at 12pm EST, an email will be sent on Jan 4 at 9am EST. Notice in this case an email is not sent on Jan 3 because a full two days haven't passed. Instead an email is sent on Jan 4 after two days and 21 hours.
Sending after a specific number of days is useful when you want to normalize the time of day people receive your emails, for instance, to optimize open rates. Because people can subscribe at any time of day, it might not make sense to send welcome emails to someone late at night just because that's when initially subscribed.
After you specify the timing of the new flow email, a blank step is added to your flow. Click Configure Message to specify the subject line, from email, from name, and content.
Change an Email's Sending Status
After you've created the content and previewed it, return to the flow detail and update the flow email's sending status to manual or live by clicking on the paper airplane icon to the left of the flow email name.
When you add an email to a flow and set it to live, emails are not queued for past flow recipients. Emails are only queued when a flow is triggered, not when a flow email's sending status is set to live.
If you'd like to queue recipients for flow emails you've added to a flow, there is the option to back-populate a flow, which will gives you some options to queue emails for past recipients based on the flow trigger.
