Bossar

Bossar is a specialized eCommerce email marketing agency focused on email and SMS. With 5+ years of experience and a proven track record across 100+ stores, we focus exclusively on retention marketing that drives measurable results.

Most of the brands we work with are established eCommerce businesses, and the majority of our clients operate in the 6- to 8-figure revenue range. This focus allows us to craft strategies built for scale, helping growth-minded brands unlock the full potential of email and SMS. Our longest-standing client has been with us for over 4 years, proof that our strategies create growth that lasts.

As a full-service email marketing agency, our core offer is done-for-you email & SMS management, which covers every aspect of retention marketing, including:

• Automated email & SMS flows tailored to your brand and customer journey
• Campaign planning, execution, and optimization
• Audience segmentation and advanced personalization
• Custom design + conversion-driven copywriting
• Deliverability monitoring and inbox placement
• A/B testing and performance optimization
• Detailed reporting and actionable insights

If your store is under $50K/month in sales or you’re not ready for ongoing monthly management, we also offer one-time flow setups and custom projects designed to match your tech stack and business needs. Whether you need a dedicated Klaviyo email marketing agency or support with another ESP, our team builds flows and campaigns tailored to your system.

With Bossar, you’re not hiring a generic provider, you’re partnering with a retention-focused email marketing agency that lives and breathes email & SMS, turning them into your most profitable growth channels.
