Weekly spam-complaint spike alert (Klaviyo)

🚨 Spam-complaint spike — 1 send over threshold this week (Jun 23–29) • Send: “We miss you — 20% off to come back” (Jun 26) • Complaint rate: 0.14% vs your 0.10% threshold • Delivered: 18,400 · Segment: “Inactive 180+ days” • Likely cause: large re-engagement blast to long-inactive recipients — the highest-risk pattern for complaints. • Suggested fix: next time, warm up in smaller batches and suppress 365-day+ inactives, or tighten to the 90-day engaged segment. Everything else this week stayed clean. I only read Klaviyo — I never change or pause your sends. Want me to pull the exact recipient segment or draft a suggested suppression list you can apply?

Yeah — how bad is 0.14% really?

It’s over the line but catchable. Mailbox providers start throttling around sustained 0.10%+, and you’re at 0.14% on one send — a single spike won’t tank you, but a repeat pattern of re-engagement blasts would. This send drove 26 complaints on 18,400 recipients; your other sends this week sat around 0.03%, so it’s isolated to the win-back audience. Cleaning up who you re-engage should bring it right back down. (Still read-only here — nothing’s been changed.)

✅ Deliverability check — all 6 sends this week (Jun 30–Jul 6) under your 0.10% threshold. Highest was the Fri promo at 0.04%. Nothing to action.

Nice, the win-back fix worked. Thanks for keeping an eye on it.

👍 Glad it landed. I’ve got this every week — you’ll get a heads-up the moment any send crosses your threshold, and an all-clear when it doesn’t. No need to check Klaviyo yourself; I’ll surface it here.
