Send email to collection of names with dynamic display names for each item

[BigE]

I have a gallery where I select multiple names using a check box which in turn will create a collection with "FullName" and "Email". This is working as expected. To break that down further, here are the properties of the checkbox:
On Check: Patch(collectEmailStudent, ThisItem, {IsChosen:true, FullName:ThisItem.FullName, Email:ThisItem.Email})
On Uncheck: Patch(collectEmailStudent, ThisItem, {IsChosen:false, FullName:"", Email:""})

I have a button on the screen that I would like to use with the send email function and I have this working, sort of. Here is the formula I have at the moment:
Office365Outlook.SendEmail(Concat(collectEmailStudent, Email & "; "), "Action Needed: Missing Faculty Advisor’s Approval of Internship Proposal", "Dear " & LookUp(collectEmailStudent, IsChosen=true).FullName & ",", {Importance:"High", IsHtml:true});

Everyone I select receives the email but what I'm trying to do is personalize each one with their own "FullName". All it is doing now is sending an email to all that are checked but only selecting the "FullName" from the first one in the list. Does anyone have any ideas that be able to point me in the right direction?

Thanks,
Eric

What if you try:

ForAll(Filter(collectEmailStudent, IsChosen = true),
Office365Outlook.SendEmail(
Email,
"Action Needed: Missing Faculty Advisor’s Approval of Internship Proposal",
"Dear " & FullName & ",",
{Importance:"High", IsHtml:true}
)
)

@BigE ,

I will leave you with @Alex_10 on this - his syntax should do the job, but a couple of points: -

• If you use Office365Outlook.SendEmailV2, it automatically detects HTML
• Email is not a good name for a field as it is a Reserved Word in Power Apps
• If your testing results in two emails to everyone, this is a known bug in Power Apps
