How to create a system-based one-time mailing
Table of Contents
A system-based one-time mailing allows you to send a mailing to a bot that accepts subscribers into a channel after the user performs one of the following actions: Subscribing to a channel, Unsubscribing from a channel, Registering for your product, Selling, or Reselling .
The newsletter is sent after the action is performed at the time you specified. If "Send only once" is not checked, the newsletter will be re-delivered to the user each time they unsubscribe and then subscribe to the channel.
Let's take a closer look at the form for adding a system-based one-time mailing:

Name
The name of the newsletter is for your convenience.
Mailing type
Select the mailing type “System disposable”
Event
Select the event after which you want to send a message.
Date and time
Select the date and time to send a message after the user completes the selected action.
Spot
Specify the spot(s) to which the mailing should be sent.
Editing rights
Select employees who can edit this newsletter.
Send only once - the newsletter will be delivered to the user only once, regardless of the number of subscriptions and unsubscriptions from the channel.
Rights of deletion
Select employees who can delete this mailing list.
Text
Enter the text of the message to be sent. Available macros:
{name} - username
{link} - the offer link specified in the Spot , in the Deals tab. This macro is useful if you want to insert an offer link, but your campaign includes multiple spots and each has a different link (⚡️Note: the macro name must match the name you specified in the Deals tab).
{manager} - manager link. This macro is useful if you want to insert a manager link, but your mailing involves multiple spots and each has a different link. The link will be taken from the Communication Channel field in the Spot settings.
{channel_link} - the channel link specified in the Spot. This macro is useful if you want to insert a channel link, but your campaign involves multiple Spots and each has a different link.
Click the "Add" button and you're done! Users will receive the newsletter at the specified time.
*We recommend creating newsletters at least 5 minutes before sending.
*If you change the spot in the campaign settings, it stops working—especially if you try to relaunch it on a different spot. This also applies to copies: the campaign only works with the spot it was originally specified for. Therefore, if you need to launch a campaign on a different spot, it's best to create it anew rather than copy it.
