We segment a lot of our emails with different characteristics. Being able to exclude by tag is helpful, but we have to make sure our lists are up-to-date AND that the tags are applied properly. There is a lot of room for error and it would be helpful if we could just exclude by a list or by a segment. Currently, the only option is to exclude by tag.
I would also like the option to send AND do not send simultaneously. For example, we do re-engagement campaigns. If someone doesn't open an email from us in 90 days, we want to exclude them. But if we're doing a regular campaign, we may need to include a segment. Need the option to send to one group and not send to another.
