Neat idea! Are you considering making future matches available for predicting as well, or do the predictions only open a couple of days before a match?
Thanks! The default calendar (without filtering) contains all 104 matches. If you choose the download option (ICS), it will appear as, e.g., ' Winner Group L vs 3rd Group E/H/I/J/K (Round of 32)'. However, if you choose the subscribe option, the placeholders will be replaced by the actual team names.
Hypera only generates the introductory paragraph in a cold email (as you must have seen on the website). How useful or spammy the rest of the email is - i.e., what the sender is trying to pitch - is up to them. If CTR and response rates increase, both of which lead to increased conversion, it stands to reason that these emails are more welcome with personalisation than what you might call spam.
