Curative Mushrooms

Client Overview

Curative Mushrooms is a fast-growing e-commerce wellness brand with an education-first email community. Email drives product launches, customer education, and a meaningful share of revenue — so inbox placement isn't a "nice to have," it's core infrastructure.

The Situation

In early 2024 — right as new bulk-sender requirements and DMARC expectations tightened across major mailbox providers — Curative Mushrooms was sending ~100,000 emails per day. Deliverability started slipping: key campaigns landed in spam, automations became inconsistent, and sender reputation trended in the wrong direction.

They didn't need new copy. They needed someone to stabilize the technical foundation, eliminate conflicts, and restore predictable inboxing at high volume.

What Was Broken

Several compounding issues were working against them:

• Authentication misalignment across sending domains (SPF / DKIM / DMARC)
• Overlapping or conflicting automation logic (Klaviyo + legacy tooling)
• Segmentation and engagement issues impacting reputation
• Monitoring existed, but wasn't configured or reviewed consistently — so problems weren't caught early

What We Did

We ran a full technical audit of their sending domains, mail streams, and lifecycle automations — then executed a stabilization plan focused on deliverability first, performance second.

• Authentication alignment: Cleaned up and standardized SPF/DKIM/DMARC across domains and senders, with reporting visibility so issues could be seen and addressed quickly.
• Automation integrity: Reviewed and corrected Klaviyo flows, triggers, and routing logic; removed conflicts caused by legacy sequences and duplicate triggers.
• Reputation protection: Implemented a controlled warm-up / throttling approach, list hygiene improvements, and engagement-based sending to protect sender reputation while volume stayed high.
• Monitoring & visibility: Tightened deliverability monitoring and ongoing review so problems were measurable, not anecdotal.

Results

Within ~3 weeks: inbox placement stabilized and became reliable and repeatable again (campaigns + automations)

Within ~1.5 months: sender reputation was fully restored and performance normalized

"John is a true professional and an absolute expert in email deliverability. Working with him has been a game-changer for our company, Curative Mushrooms.

His understanding of SPF, DKIM, DMARC, and advanced routing inside Klaviyo was exactly what we needed. He didn't just fix the issues — he built systems that continue to monitor and improve deliverability across platforms.

Any business would be lucky to work with him. Reliable, proactive, and worth every penny." — Oliver, CEO, Curative Mushrooms
