1 point@Tsunami is correct. In the case of @greenamit I was able to confirm that the server did not block the specific IPs. It's hard to figure out how many users have issues with this, since there are still a lot of people using Units without any problems. Anyhow just wanted to let you all know that I checked with my hosting provider and they confirmed that there where no blocks or problems on their side.
1 pointJust wanted to say thanks (and I bought you a beer) for this powerful and simple-to-use workflow! I recently needed to send a large amount of emails based on an Excel-sheet with relevant information in several columns. It was pretty straightforward to extract the needed data with your workflow and create the text for each email.
