Send email
In this node you select an email which will be sent to contacts as soon as they arrive at the node.
- The email itself can be previewed or edited through opening the properties pop-up.
- If you open an email from a program, the program name is displayed at the top and you can return to the program via the linked program name at the top.
In transactional programs, Send email nodes can process a maximum of 250,000 contacts coming from New contact, Data change or On auto-import (this limitation only applies to programs starting with the On auto-import node that were created before September 13, 2021) entry points. Any more contacts than this, and the program will be put into fail-safe mode.
We strongly recommend that you break up imports that contain more than 250,000 contacts into smaller blocks, or freeze any programs that might be affected until after the import has been completed.
Emails used in programs are of the type On program event. Other email types can be selected from the Automation Center are also available for selection, but they will lose their recipient source and scheduling page once selected.

- Select or create a contact list - You can create a new contact list or select an already existing one. Contacts will be added to or removed from the selected contact list.

What to do with contacts arriving at this node?
- Add contacts to the contact list - Contacts will be added to the selected contact list.
- Overwrite existing list with contacts who arrived at this node (even with single contacts) - The selected list will be overwritten with contacts arriving at this node even if only a single contact arrives at it.
- Remove contacts from the contact list - Contacts will be removed from the selected contact list.
The Update contact list node uses the name of the contact list as key, meaning that the program cannot update itself if the selected contact list is renamed. Therefore, you have to manually enter the new name of the contact list into the node in all relevant programs, otherwise a new contact list will be created with the old name.

Web Channel - add
Important: Your Automation Center Web Channel node will be migrated to the new one on your account between July 20 and August 5. It might happen that during this period you will not be able to distribute Tactics containing Web Channel campaigns. In this case, please contact Emarsys Support.
If you are using Web Channel, you will also see this node. It adds contacts who pass through it to the selected Web Channel campaign.
When adding a Web channel - add node to your program, please consider the following recommendations:
- Only those Web Channel campaigns are available for selection, where the recipient source is set to Automation Center.
- Automation Center cannot manage the status of Web Channel campaigns. For this reason, you need to activate a Web Channel campaign before adding it to an Automation Center program.
- You can use multiple Web Channel campaigns in a single Automation Center program.
- A single Web Channel campaign can be used in multiple Automation Center programs.
- All contacts passing through a Web Channel - add node must go through a Web Channel - remove node, too. We recommend inserting a Quick filter, Wait, Participation check node or another kind of filter node between the Web Channel nodes that checks whether contacts fulfilled a specific requirement before they are removed from the Web Channel campaign.
- Make sure that your Web Channel campaign does not contain any unacknowledged errors. For more information, see Fixing unacknowledged errors in active Web Channel campaigns. For more information, see Creating a Web Channel campaign for Automation Center.
