The best days to send the press release are from Tuesday to Thursday. This is because journalists have time in their hands during these days. They have finished pressing tasks and are looking for better stories. They are genuinely interested in picking out a new story to work on. It is during these days that the chance for a press release to be opened by a journalist is maximum and has an effective distribution timing. The opening rates are very high in the mentioned days. There is no 100% guarantee that the press release will be opened but there is a high chance that the journalists will have the time to do so.
