BigMailer

BigMailer is built for franchise operations and agencies that juggle multiple client accounts under one roof. You can manage over 100,000 subscribers across different client brands, with white-label features that put your agency's branding front and center. The platform supports up to 100 team members with granular permission levels, so you can give junior staff access to specific clients without exposing everything.

It's ideal for agencies dealing with franchise networks or regional office structures where multiple team members need to coordinate on different accounts simultaneously. The subscription model scales with your client base, and the unified dashboard makes client onboarding faster than managing separate platforms. Smaller boutique agencies that want more control over client access might find it overkill, but for growing operations with deep team collaboration, it fills that gap well.
