Marketers are abandoning the batch-and-blast approach in favor of a more refined, selective one. The best marketers carefully develop their target list before putting together an email. This is what enables them to send the most relevant messages to the most fitting recipients for the highest open rates.
The same approach is especially important with InMails, where you’ll quickly lose credibility if you’re just “spraying and praying”. Make sure you have a reason for every instance of outreach. Research the LinkedIn member and ask whether you can offer value by sending a message. If the answer is no, cross that recipient off your list for now.
