Before you can send bulk emails from your computer, think about who you will send your newsletters to. If you have a list of buyers or clients, you can start sending them since you are in relationship with those people. Only don't forget about the unsubscribe link. Include it into each mail newsletter and care about managing opt-out requests. But what if you're just starting your online business and don't have any mailing list yet? Many online marketers buy email addresses or harvest them on the Internet. On my opinion it's not the right way to go because if you send messages to people who don't know who you are, they are likely to consider your emails as spam and hit 'spam' button in their email clients. If your newsletter generates many spam complaints, this hurts your sender reputation and deliverability. But the worst thing is that the ISP Spf lookup limit can shut your account down for sending spam emails. Furthermore, you can't be sure that all email addresses you buy are good. You can hit a spam trap account, be labelled as spammer and come into troubles with your ISP. Thus, the best way to get an email list is us a signup form on your own website or blog. People will come to your site and subscribe consciously. This is what is called permission in email marketing. People permit you to email them by giving you their email addresses. When you see the number of your subscribers grow, you can start sending bulk emails to your list. Now you have to choose bulk email newsletter software that meets your needs best. I would recommend that you choose a desktop email sender program because it allows you keep your email list and messages in-house without uploading them to any 3rd party database. Another great feature you should look for in email sender software is tracking capabilities. If you are serious about email marketing, you can't afford to not track your email campaigns. If you don't know how your readers like or dislike your message, you won't be able to send them what they need or take any profit from your list. If your bulk email software has no built-in email tracking feature, you can find many email tracking services on the Internet and choose the service that suits you best. Usually email tracking reports tell you who opened your message, who clicked links in the message, who printed and who forwarded the message. Some email tracking services also provide you with the report about the email clients your recipients used to open your email -- you will know which email clients/web based accounts you need to tailor your email for. Don't forget to test your email newsletter prior to sending it to the whole list. It's very simple. Setup email accounts with big free ISP like AOL, Yahoo, Hotmail, Gmail and send a copy of your email to your test email addresses. See if the message arrived into the Inbox or Junk folder. Spf lookup limit If the message is treated as junk mail, you have some food for thought. Probably your email has spam looking content, or links you use in the email are from blacklisted domains, or HTML code is broken. Tailor and test your message until it is delivered into the Inbox. Then send it to the whole list.
