There are many vendors out there who sell lists or rent them (though renting means that the list seller maintains ownership and control of the email list). These are collections of email addresses that the vendors sell to any business or individual who can pay the fees. Your email list is considered to be a purchased or shared list if it’s provided to you by a third party, like an email list vendor or affiliate. There's a few ways that vendors build these non opt-in email lists.
Try different hyperlinks to see what works best for your audience. You might create three different groups and send each link to your home page, product pages, and blog. You might also try CTA links with different wording, or test an email that includes the same link two or three times. The data will tell you what works. Low click rates may mean your emails aren't compelling, or the information isn't useful for that audience.
You could use your Hotmail, Gmail or Yahoo accounts, but if you need something professional and fool-proof and want to avoid being labeled a spammer, it’s a far better idea to use an email blast program provided by a professional email marketing company such as Benchmark Email. Benchmark’s partnerships with elite consortiums like The Email Sender & Provider Coalition (EPSC) and leading delivery experts like Return Path give you the best chance of reaching a prospect’s inbox, which is a major challenge in email blast marketing. Benchmark Email even has built-in data merging features, which allow you to import contact information from different databases so you don’t need to re-enter long email lists. Besides this, you can also customize your mails in easy-to-use HTML editors before sending them to your customers and prospects.

Work as a team from the same Mailjet account. Separate your activities using sub-accounts, invite an unlimited number of users, and control what they can do by defining their roles and advanced permissions. Each team member will be able to work independently, within a well-defined scope of abilities. Maximize your efficiency, maintain full control.
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.
