The mailshot campaign cannot be released as a whole. All mailshots that are to be sent as a part of the campaign must be released gradually.
Mailshot Campaign with unreleased or missing mailshots
If any mailshots connected to the mailshot campaign were not release or connected to the frame, it can affect the course of the mailshot campaign. The following examples describe some possible situations and their consequences.
Situation A
If the initial mailshot is not released, the mailshots that are connected to it will not have a target group and therefore cannot be sent (even if they are released).
Situation B
Several mailshots after a reaction are connected to the initial mailshot, one of them does not have a connected mailshot. The mailshot campaign behaves as if the mailshot is connected here: If it is a reaction type with a higher priority, then dispatching the rest of the mailshots after a reaction is halted until its validity ends.

- the situation has not been resolved by the user - 
the mailshot will only be sent after the set validity of the frame with the reaction after the transaction.
Situation C
If an unreleased mailshot is in the mailshot campaign, then the campaign will be processed according to the scheduled scheme and it ends at the point with an unreleased mailshot.
Picture 8 - The example of an unfinished, released mailshot campaign - forgotten unreleased reaction mailshot - the situation has not been solved by a user - 
nor mailshots, which should follow it, will not be sent.
Situation D
A user noticed the unreleased mailshot (see situation C) and released it before its validity expired. The mailshot will be sent according to the original scheduling. This mistake will not take effect on the rest of the campaign.
Situation E
Only one frame (without a mailshot) is connected to the previous mailshot. This part of the mailshot campaign will be ignored and does not affect other parts of the mailshot campaign.
