I don't think there's any report at present that will do this.

The following SQL should extract the required information. It just needs to be put into a Jasper Report:

 select title.name as title, firstName.value as firstName, lastName.value as lastName, cd.value as emailAddress
from entities e
join contacts c on c.contact_id = e.entity_id and c.arch_short_name = "contact.email"
join contact_details cd on c.contact_id = cd.contact_id and c.arch_short_name = "contact.email" and cd.name = "emailAddress"
left join entity_details firstName on firstName.entity_id = e.entity_id and firstName.name = "firstName"
left join entity_details lastName on lastName.entity_id = e.entity_id and lastName.name = "lastName"
left join entity_details titleCode on titleCode.entity_id = e.entity_id and titleCode.name = "title"
left join lookups title on titleCode.value = title.code and title.arch_short_name = "lookup.personTitle"
join contact_classifications cc on c.contact_id = cc.contact_id
join lookups l on cc.lookup_id = l.lookup_id and l.arch_short_name = "lookup.contactPurpose" and l.code = "REMINDER"
where e.active = true and e.arch_short_name = "party.customerperson"
