Not really. Email addresses that belong to an "opt in" list have opted to receive emails from, say, the list-purchasing company -- not your company. Even if the opt-in process includes language like, "Opt in to receive information from us, or offers from other companies we think you might enjoy," the fact is the recipient doesn't recall having a prior relationship with you, specifically. This makes it highly likely for the recipients to mark you as "spam" when you arrive in their inboxes. Hey, if they don't recognize you or remember opting in to communications from you ... can you blame them?
You don’t even have to think you’re a spammer to feel bad. Many of us feel bad just for sending too many emails. Often solopreneurs are downright terrified of sending an email update to their subscribers. They say they don’t know what to say, but I think it’s that they’re afraid, somehow, that they’re bothering their subscribers. They aren’t sure they deserve to be in their inboxes, even if those same people signed up for their emails (through a double opt-in process, of course).
It’s important to note how a number of growing trends revolve around content of value – not promotional content. Things like personalization and subscriber lifetime value, bite-sized content that’s easy to digest, stronger narratives and storytelling, richer experiences… that’s all key to crafting highly engaging emails that will grow your open and engagement rates.
Another collection method happens when list vendors buy emails lists from industry trade shows (or other events) where people give their info during the registration process. This is not the same thing as folks who signed up with you, directly, at your trade show booth! This is where list vendors purchase the entire registration list, from the trade show, itself. http://www.emailvendorselection.com/wp-content/uploads/2014/12/email_drips_hobsons.jpg
Internet service providers (GMail, Yahoo, etc.) and anti-spam organizations create the spam traps to prevent spam from reaching people’s inboxes. The important thing for everyone to remember is if you use a purchased list, you are technically spamming the people on that list. Spam is unsolicited email and those people did not request your information.
Rob, you don’t say who ‘booted’ you from using it. A significant GDPR factor is non-profits having to consent/re-consent those on established email lists and experiencing significant proportions of lists being lost because people miss the notifications or are too busy to fill in yet more forms. However, I have found a few using a ‘one-touch’ re-subscription button that takes immediate effect, without the recipient having to do anything else. It would appear that the re-subscription rate is higher, the easier it is to activate. On enquiry, I was told that they were using mail chimp for this.
Julie Ewald recommends moving away from sending generic content to your whole email list via e-blast entirely. With a little elbow grease, you can utilize segmentation and start sending off tailored messages to each of your lists with content that’s relevant, valuable, and designed to resonate with the kind of recipients that make up each segment.
