Once you launch a sequence in Salesforge, its structure becomes locked. However, you can still make certain changes to existing steps, update contact information, adjust delays, and manage contacts. This article explains what remains editable after launch and how those changes affect contacts already enrolled in your sequence. ## 1\. What can you change after launching a sequence? Here's an overview of the changes you can make to a live sequence:

Setting or action	Editable after launch?	Effect on contacts already in progress
Add a step	No	Not supported.
Remove a step	No	Not supported.
Move or reorder steps	No	Not supported.
Add, remove, or move a Stop on Reply step	No	Not supported.
Change condition branches	No	Not supported.
Edit message templates	Yes	Updated content is used for steps that haven't been sent yet
Edit LinkedIn connection notes	Yes	Updated notes are used for future tasks
Change the delay of an existing step	Yes	Already-queued, unsent tasks are rescheduled using the updated delay.
Change the sequence sending schedule	Yes	Tasks already queued retain their previous schedule. New tasks follow the updated schedule.
Remove a sender profile	No	The sender profile cannot be removed from a launched sequence.
Remove mailboxes from a sender profile	Possible outside the sequence editor	Contacts assigned to removed mailboxes will be unable to proceed with subsequent steps.
Add new contacts	Yes	New contacts can enter the already-launched sequence.
Remove existing contacts	Yes	Removed contacts stop progressing through the sequence.
Update contact variables	Yes	Updated values are used by steps that haven't been sent yet.
Launch the sequence again	No	Launch is a one-time action and is locked after the initial launch.

**Important:** You don't need to relaunch a sequence for supported changes to take effect. Each change is applied according to the behavior described above. ## 2\. Editing existing steps Although you cannot change the structure of a launched sequence, you can still edit the content of existing messaging steps. For example, you can: - Update email templates, including subjects and message bodies. - Change LinkedIn message templates. - Edit LinkedIn connection notes. These changes apply to steps that haven’t been completed yet. ### Can I add or remove steps? No. Once a sequence has been launched, you cannot add or remove steps. You also cannot move or reorder existing steps. This restriction applies to all step types, including: - Email steps. - LinkedIn messaging steps. - LinkedIn connection request steps. - Delay steps. - Condition and branching steps. - Stop on Reply steps. The sequence structure and execution flow are locked after launch. ### Can I change condition branches? No. You cannot retarget or modify condition branches after launching a sequence. If you need to change the sequence flow, add new conditions, or rearrange its steps, you'll need to create a new sequence with the desired structure. ## 3\. Changing step delays You can change the delay or waiting period of an existing step after launching your sequence. Unlike changes to the sending schedule, changing a step's delay also updates the scheduled time of tasks that have already been queued but haven't been sent. **Example:** Suppose a contact is scheduled to receive an email two days after completing the previous step. You change the delay to three days. The contact's already-queued task will be rescheduled according to the new three-day delay. You don't need to relaunch the sequence for this change to take effect. ## 4\. Changing the sending schedule You can also update the sending schedule of a launched sequence, including its configured sending days and hours. However, there is an important distinction: **Tasks that have already been queued will follow the previous schedule.** The updated schedule applies to tasks that are queued after you make the change. For example, if you change your sending schedule from Monday-Friday to Monday-Saturday, tasks that were already queued will retain their original scheduled times. Newly queued tasks will follow the updated schedule. ## 5\. Sender profiles and mailboxes Sender profiles require particular attention when working with a live sequence. ### Can I remove a sender profile? No. It’s not possible to remove a sender profile from a sequence that has already been launched. ### What happens if I remove mailboxes from a sender profile? Removing mailboxes from a sender profile can affect contacts that are already progressing through your sequence. For example, if a contact is assigned to a mailbox that is subsequently removed from the sender profile, the contact may no longer have an available sender for its next step. **We recommend keeping the mailboxes associated with a live sequence connected until the contacts assigned to them have finished progressing through it.** Be careful when changing mailbox assignments in an active sender profile, and make sure you have considered the impact on contacts already in progress. ## 6\. Updating contact variables after launch You can still edit contact information and variables after launching a sequence. This is useful when you need to correct or update information that will be used in upcoming messages. Contact variables can be updated through: - The Salesforge UI. - The public Salesforge API. ### When do updated variables take effect? Salesforge fetches a contact's variable values when a step is sent. This means that as soon as a variable for a contact is updated, any steps sent in the future will be sent using the updated variable. ## 7\. Can I launch an already-launched sequence again? No. Launching a sequence is a one-time action. Once a sequence has been launched, the Launch button is locked and cannot be used again. You don't need to relaunch a sequence to apply supported changes. Updates to existing messaging templates, step delays, sending schedules, and contact variables are handled according to their respective rules. If you're trying to click Launch again and nothing happens, check whether the sequence has already been launched. This is expected behavior, as the sequence cannot be launched a second time. If the sequence is launched but isn’t running, you can also check whether it’s paused on the Sequences page of Salesforge. ## 8\. What if I need to change the sequence structure? If you need to add, remove, or rearrange steps, change condition branches, or modify the overall flow of a launched sequence, these changes are not currently supported. The recommended approach is to create a new sequence with the desired structure. You can then add the appropriate contacts to the new sequence. Before doing so, review your existing contacts and their progress in the original sequence to avoid sending duplicate messages or having contacts progress through both sequences unintentionally. ## Still need help?
