Back in the early days of email we were more worried about choosing the perfect username than we were about marketing. In fact I distinctly remember being more stressed over forwarding a chain email to five other people, because it’d somehow improve the chances of my high school crush declaring their passionate love for me, than I was about whatever newsletter found its way into my inbox.
There are organizations called blacklists like Spamhaus as well as other filtering organizations like Cloudmark and Brightmail. Email clients like Yahoo and Gmail and Hotmail rely on them to help block spam (yay!). These blacklists leave spam traps or honeypots for shady list sellers to collect. Then, if one of those email addresses ends up in your purchased list, you're in big trouble! It's like having bad credit - it can take a long time and a lot of hard work to rebuild trust with blacklists and until you do, you'll have poor delivery results even if you've stopped using the purchased email list.
If you want to operate an email blast campaign as a part of your marketing strategy, then you need to send the emails out regularly. If it is too long between emails, then the recipient might not even remember what your content has to offer. However, you do not want to send them too frequently. If the consumer is getting an email from you every other day, then they might get annoyed and stop reading altogether.
Testimonials – If you work with contractors or freelancers, you can reach out to them to offer your testimonials in exchange for a link. Moreover, if you are using consultants’ or specialists’ services, you can also do the same as you do with contractors. Lastly, if there are customers who are happy with your product or service offering and they do not mind you linking to their site, this could be a good opportunity for your business.
