What sets SOLID apart

The unfair advantages your email program gets with us

Most agencies send campaigns. We build AI-augmented email systems — smarter automation, deeper lifecycle coverage, and a level of optimization that traditional teams can't match.

Opportunity detected

“Brand keywords DE” has 38% lower CPA than non-brand. Shift 12% budget to capture high-intent volume.

Bid adjustment

Mobile bids increased +15% for top 6 converting ad groups. Projected +22% conversions.

AI-powered send-time & subject line optimization

We use AI to analyze subscriber behavior patterns, test subject line variations at scale, and optimize send times down to the individual level. The result: higher open rates, better engagement, and inbox placement that improves with every send — not a one-size-fits-all blast schedule.

Weekly update: Search campaigns hit 142 conversions (+18% WoW). ROAS at 4.7x.

We paused 3 underperforming ad groups and shifted budget to top performers. New ad copy test launching tomorrow.

Weekly performance insights, not monthly reports

Most agencies send a PDF at the end of the month and move on. We share performance updates every week — with context on what's working, which flows are converting, and what we're testing next. You'll always know what your email channel is producing and where it's headed.

Deliverability issues caught before they hurt you

Our monitoring systems track inbox placement, bounce rates, spam complaints, and sender reputation in real time. We catch deliverability problems before they snowball — warming domains, cleaning lists, and adjusting authentication so your emails land where they should.

Full lifecycle strategy, not just newsletters

FAQ

Frequently asked questions

What makes your email marketing approach different?

We treat email as a revenue channel, not a megaphone. Every campaign and flow is built around your customer lifecycle — from first signup to repeat purchase. We combine AI-powered optimization with hands-on creative strategy to drive measurable revenue, not just opens and clicks.

How quickly can I expect results from email?

Quick wins — like optimizing existing flows, fixing deliverability issues, and improving segmentation — often produce results within the first 2–4 weeks. The real compounding happens over 2–3 months as we build out your full automation stack and refine based on data.

Which email platforms do you work with?

We work with all major platforms including Klaviyo, Mailchimp, HubSpot, ActiveCampaign, Brevo, and more. If you are considering a migration, we can also manage the entire transition — including list transfer, flow rebuilds, and template redesign.

Do you write the email copy and design the templates?

Yes — our team handles everything from strategy and copywriting to visual design and HTML/CSS coding. We build mobile-responsive, on-brand templates and write conversion-focused copy that's tested and iterated continuously.

How do you handle list growth and subscriber acquisition?

We optimize your signup touchpoints — pop-ups, embedded forms, landing pages, and lead magnets — to grow your list with high-quality subscribers. We also build segmentation and tagging from day one so every new subscriber enters the right journey.

What kind of reporting can I expect?

Full transparency with flow-level and campaign-level dashboards showing revenue attribution, engagement metrics, deliverability health, and list growth. We break down exactly which emails are driving sales and where the next opportunity is.

Ready to turn email into your most profitable channel?

We'll audit your current email program, show you where the biggest revenue opportunities are, and map out a plan to capture them. No commitment, no pitch deck — just a clear roadmap.
