Helpful for some of the use case, not all. Email population was patchier than I expected from the listing. Would consider buying again if a credit or refresh is offered for the bad rows.
Sorry the file didn't fully land for you, we'd like to dig into the specific rows that failed and refund or re-export them for you. Drop a ticket via Help → Contact Support with the specific issues and we'll get a credit applied + a fresh export queued.
