Be careful when marking SPAM in your inbox. Is it really spam, or are you just sick of seeing it, not sure where it came from, or forgot you signed up for it?
Come on, you know what real spam looks like. But when you rate an email as spam, it hurts the company's credibility, and sometimes the relationship with their email management system. If a company sends more emails than you'd like to receive, that does not qualify as spam.
Take a moment to see if there are options for which emails to receive and how often, or simply unsubscribe from them all. If you're getting tired of seeing them come in faster than you can read them, but don't want to unsubscribe, check your email settings and see if you can filter them through your inbox and into a separate folder to get to when you can.
On the flip side, as a business make sure you let people know how many emails they should be expecting when they sign up, and give them as many options as possible to help segment them into categories they care about.
Always be checking in on your email system's analytics to see which emails are getting unsubscribes and spam reports, and see if you can identify a trend to improve your open rates.
For me, it has been a spam-free summer!
