Discover the top affordable email marketing tools for agencies, including how Flight helps you send up to 50,000 emails for just $30/month.
Running email campaigns can be tough for agencies. Most tools charge per contact, which quickly becomes expensive if you manage many client lists. The good news? There are affordable email marketing platforms that let you send bulk emails, run campaigns, and track results—without draining your budget.
In this guide, we’ll explore the 20 best low-cost email marketing tools for agencies in 2025. These tools balance affordability with the features you actually need, helping agencies deliver results for their clients.
Why Agencies Need Affordable Email Marketing Tools?
Agencies handle multiple clients. That means more lists, more campaigns, and higher sending volume. Traditional platforms like Mailchimp or ConvertKit charge heavily once subscriber counts grow.
Choosing budget-friendly tools allows agencies to:
- Keep client costs low without cutting quality
- Scale campaigns without worrying about subscriber limits
- Deliver value fast with easy-to-use tools
- Stay profitable with predictable costs
