If you want to use the advanced launch options, such as testing different versions of your email on a small percentage of recipients before sending the final mailing, click Advanced Scheduling.
Advanced scheduling is not supported for email campaigns with audiences over 5 million contacts.
Before you can take advantage of any of the features here, you will have to Generate the launch list manually. Once this is displayed in the table, you can proceed with your launch.
Click the Invalid address column to open your Bounce Settings page, and click Estimated recipients to view the launch list

Once you have switched to Advanced Scheduling and performed any actions there (such as generating the launch list), you will not be able to switch back to Simple Scheduling.
On-event scheduling for recipient sources generated through an event
If your email campaign is set to be triggered by an event, the Scheduling page simply lets you decide whether to send the emails exactly on the event or a certain time before or after.

In this way, you can send an email one day before an anniversary event, for example, or a day after a registration.
After you have set the schedule, click Activate to enable the campaign. From this moment, it will send an email every time the trigger event occurs.
On-date (including on-birthday) emails are sent each day at the same time in the account default time zone. This setting is not affected by changes to the time zone on the profile page of the logged-in user.
Recurring scheduling
In most cases, recurring campaigns are created using the Automation Center Recurring filter entry node. However, you can set one up in the Email Campaign module, but you must ask Emarsys Support to set the actual launch time.
If you have set up such a recurring campaign, the scheduling page is replaced by controls asking you to define when the child campaign is created and who should receive an alert. This is designed to give you time to check the child campaign and correct any errors in time for the launch.

Pausing and resuming launches
While your email campaign is being prepared and being sent out to all the recipients, you can still halt the email sending process by clicking Pause. To continue with the launch, click Resume.
If you pause a campaign after some emails have been sent out, these contacts will still be listed in the Analysis pages. Once all the email have been sent, you can no longer stop or recall any of them.
To pause an on-event campaign, open the Scheduling page and click Deactivate at any time.
Time-based limitation of campaign launch
When a campaign is created, a lot of processes are started in our databases that can put a heavy load on them. In order to manage the load, we are disabling all campaigns which are not launched within 30 days of their creation.
If you want to launch such a campaign, you will need to copy it and then launch the copy.
