Direct email marketing costs are pretty affordable for most small businesses, even if you go through an agency. Most agencies will cost $300 to $700 for a small business's basic email marketing. If you want to add special graphics, content, and do a little AI on the side, you might pay around $1,000 to $1,500. 

Even if you do it yourself, the range of pricing will be fairly similar if you're a small business. You can DIY your own email marketing campaign for $100 to $1000 in most cases. Of course, this is more time-consuming and also relies on you to do it all. 

Regardless of what you choose to do, it's important to remember that email marketing is a smart move. It's actually the most effective small business option on the list in terms of ROI. (4200% on average, yo!) So, you can expect it to pay for itself.
