use google script… is faster and free, join the filtered emails, and set a trigger column with that joined list… then have an onChange trigger to run the script… script will split that value, and send emails
no, you don’t check users… example: if user age is greater than 18 show user email
for multiple conditions use multiple if else columns but this time instead of showing the user email… show 1
then use math column to add results… if sum equal number of filters then show user email
Put your conditional logic in the table with an IF column. Not a filter. Then you can create a Joined List column to merge all emails into a single column that you can pass with a webhook.
