Laura at WttW has put together an excellent breakdown.

Let's Talk Reengagement

I appear to have written a lot about about re-engagement on the Email Geeks slack channel the last few days. The problem with slack is it’s not great at archiving or keeping information in an accessible, searchable manner. So, I’ve pulled together the answers, rearranged it, made it slightly more coherent and a little less stream of consciousness, so I can reference this when the topic comes up again.

The future of email deliverability is not about sender reputation. It is about recipient preferences.

Laura Atkins' keynote from Mautic world conference covers the fundamental shift happening in inbox filtering and what marketers need to do about it.

If you send email, you need to watch this.

Andrew Bonar talks about the recent global Gmail spam filter failure.

"The lesson from this weekend is clear: our entire communication infrastructure relies on opaque, AI-driven filters that we don’t control. When those filters fail, they don’t just stop working, they turn on us."

🚀 Khi SaaS tăng trưởng, chiến dịch outbound không còn ổn định: một số “bùng nổ”, vài chiến dịch chết nhanh. Bài học: độ tin cậy của outbound phụ thuộc nhiều vào khả năng deliverability hơn nội dung. Cần tối ưu email, danh sách và cấu hình để duy trì hiệu quả. #Outbound #Marketing #SaaS #TiếpThị #KinhDoanh #EmailDeliverability

Ý tưởng công cụ chẩn đoán chỉ đọc, kiểm tra sức khỏe domain, hiển thị điểm deliverability, giải thích bằng tiếng Anh‑Việt, và đánh giá nội dung email tránh spam. Các dev dùng SES có cảm nhận gì? #AmazonSES #EmailDeliverability #SaaS #CôngCụ #GiaoNhậnEmail #Email #Deliverability

🚀 Khởi chạy MVP, lo lắng email chào mừng & đặt lại mật khẩu bị lọc spam do dùng domain mới. Bạn cần: xác thực SPF, DKIM, DMARC; dùng dịch vụ gửi uy tín; warm‑up domain; kiểm tra inbox với công cụ. #TransactionalEmail #EmailDeliverability #MVP #Startup #EmailMarketing #ThưGiaoDịch #GửiMail

My domain `kupiapps.xyz` was flagged and suspended on the anti-abuse list. Registrar support advised me to request removal via their site. I clarified I’ve removed it from Spamhaus and added records to prevent spoofing, providing my server IP.

Người dùng mới mua VPS nhưng IP bị UCEPROTECT đưa vào danh sách đen, gây lo ngại về khả năng gửi email cho máy chủ thư sắp thiết lập. Người này nghi ngờ UCEPROTECT là lừa đảo và muốn biết liệu các nhà cung cấp lớn có quan tâm đến danh sách này không, hay có thể bỏ qua một cách an toàn?
