The Short Answer
When you send an email to multiple recipients from Marvin, each contact receives an individual email. The other recipients are therefore not visible in the received email — it is the equivalent of a blind carbon copy (BCC) send.
In other words: no one will see that other people received the same message.
How Does It Work in Practice?
Whether you send an email from:
a candidate or contact profile,
the Kanban view (multi-selection),
or a list,
...Marvin sends a separate email to each recipient. Each person receives their own email, with no trace of the others.
What If I Add Someone in CC in the Template?
If you have configured a CC field in your email template, the person in copy will be included in each individual send. They will therefore receive as many emails as there are recipients.
⚠️ If you put a colleague in CC on a group send to 50 candidates, they will receive 50 emails.
Good to Know: Variables in Group Sends
If your template contains process-related variables (e.g.: {{job title}}, {{company linked to the process}}), and the candidate is in multiple simultaneous processes, Marvin will not know which process to use and the email will result in an error.
In that case, two options:
Remove the relevant variable from your template for that send,
Manually replace the variable with the desired text.
