Advanced Sending & Segmentation Features Request

We would love to request more advanced sending and segmentation capabilities, including:

• A true suppression/exclusion list for campaigns

• Custom audience segmentation

• The ability to add tags to customer profiles and segment based on those tags

• Support for syncing or merging Shopify customer tags into TxtCart (or updating tags via CSV upload)

• The ability to schedule campaigns for a specific send time, ideally with support for time zone–based delivery (for example, 5pm local time for each recipient)

These features would dramatically improve our ability to run segmented promotions without oversending or alienating customers, especially during high-volume sales periods.
