Here's what I've been told so far: Send them out on Tuesday, Wednesday, and Thursday. Use Mondays and Fridays as last resorts and NEVER distribute on weekends. Between 3am and 6am EST is prime time to release because it's before the news outlets have their morning deadlines to hit. Always put a link in the first summary sentence because this is sometimes all that will get read. Don't forget to add social media links where relevant. Do you have any other tips to add?
