Email Deliverability That Gets Your Campaigns Into Inboxes, Not Spam Folders.

A campaign landing in spam is a campaign that doesn't exist. We audit, fix, and continuously monitor email deliverability for D2C brands — repairing sender reputation, implementing technical authentication, and keeping your Klaviyo emails reaching inboxes consistently.

Email Deliverability from Authentication to Ongoing Reputation Management

🔐
Email Authentication Setup
SPF, DKIM, DMARC, and BIMI implementation — the technical authentication stack that proves to Gmail, Apple Mail, and Yahoo that your emails are legitimate and protects your domain from spoofing attacks.
🧹
List Hygiene & Segmentation
Systematic list cleaning — removing spam traps, hard bounces, role addresses, and chronically unengaged contacts — combined with engagement-based send segmentation that protects your sender reputation on every campaign.
🔥
Domain & IP Warmup
Structured warmup schedules for new sending domains or IP addresses — gradually increasing volume while maintaining positive engagement signals — establishing positive sender history before scaling to full list deployment.
📥
Inbox Placement Testing
Pre-send inbox placement testing across Gmail, Outlook, Apple Mail, Yahoo, and international providers — identifying deliverability issues before campaigns deploy, not after engagement numbers disappoint.
🛠️
Sender Reputation Repair
For brands with damaged sender reputation — high spam complaint rates, blacklist entries, or Gmail promotions tab placement — we run structured reputation repair programs with phased volume reduction, engagement re-activation, and monitoring milestones.
📊
Deliverability Monitoring & Reporting
Ongoing monitoring of spam complaint rates, bounce rates, inbox placement percentages, and blacklist status — with weekly deliverability health reports and proactive alerts when signals deteriorate before they become crises.

Frequently Asked Questions

Key signals include: open rates declining over 3–6 months without an obvious content reason, Gmail Postmaster Tools showing domain reputation as Low or Bad, spam complaint rates above 0.1% (Google's threshold for deliverability impact), bounce rates above 2% on campaigns to your engaged segments, or Klaviyo showing increasing unsubscribe rates. Any of these signals warrants an immediate deliverability audit — the longer a reputation problem runs, the longer the recovery takes.

DMARC is an email authentication protocol that tells receiving mail servers what to do when emails claiming to be from your domain fail SPF or DKIM checks. Without DMARC, anyone can send email pretending to be your brand. Beyond security, Google and Yahoo's 2024 requirements mandated DMARC for bulk senders — non-compliance results in deliverability penalties. We implement DMARC in monitor mode first to observe the impact, then progressively enforce it through quarantine to reject policies as your authentication signals stabilise.

Every email you send to an invalid address, a spam trap, or a chronically unengaged contact sends negative signals to Gmail and other inbox providers. These signals lower your domain's sender reputation, causing your subsequent campaigns — even to your most engaged contacts — to land in spam or promotions tabs. Regular list hygiene removes these reputation-damaging contacts, and engagement-based segmentation ensures you only send to contacts whose behaviour signals genuine interest, maintaining the positive engagement ratios that protect deliverability at scale.

Yes — reputation recovery is achievable but requires patience. The process involves: complete pause on sending to the full list, aggressive list segmentation to identify the most engaged 5–10% of contacts, structured re-engagement program limited to this hyper-engaged segment, gradual volume expansion over 8–12 weeks as engagement signals improve, and parallel authentication and list hygiene fixes. Full recovery from a significantly damaged reputation typically takes 60–120 days of disciplined execution.

Klaviyo-specific optimisation covers: suppression list management and automatic suppression of hard bounces and spam complaints, send-time optimisation to reduce list fatigue, engagement-based segment definitions that match Google's engagement signals, sunset flow configuration for chronically unengaged subscribers, and campaign sending limits that prevent volume spikes that trigger filtering. We also review Klaviyo's built-in deliverability dashboard monthly and address any metric deterioration before it compounds.
