Marketers don’t always automatically receive notifications when they’ve been blacklisted, so it’s up to the marketer to monitor their brand’s email sending reputation. There are a number of free online resources that marketers should utilize to check their blacklist status before sending an email blast, such as Barracuda Reputation Block List or MultiRBL.
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.
Note: If you want to attach additional files, such as a .pdf, we recommend that you store these files on a cloud storage service, such as Dropbox or Google Drive, and linking to these files within your blast. We do not support file attachments to an email blast as these file types tend to be larger, increasing your chances of triggering spam filters and preventing your blast from reaching your recipients.
While almost all reputable email service providers work very hard to make sure that your emails are not blocked by major ISP’s, they can’t control whether or not your emails hit the inbox or the spam box. Although most will help you by providing a quality score to help you determine availability, getting whitelisted is the most effective way to ensure that your emails get delivered properly.
Watch the growth of your list. Is your email list growing or shrinking? If more people are unsubscribing than are registering to your list, it's a good sign that you need an entire strategic overhaul on your email policies. If there are a lot of people unsubscribing it could be because your content is not relevant to the people that you're sending it to. In this case, try to segment your list differently or change the type of content that's being delivered through your email blasts.
