This is one of the most underutilized and under-recognized areas of email marketing, especially for businesses just starting to scale their outreach efforts. And here’s the not-so-simple reality? You can invest hundreds or thousands of dollars in email tools, fancy templates, or prospect lists—but if your sender reputation is questionable, none of it will mean a thing.
