The List-Unsubscribe header: why it's essential in 2026? If you send marketing emails without this header, your sender reputation will suffer. 📧 What is it exactly? → A hidden email header (RFC 2369, since 1998) → Allows webmail clients to display a standardized "Unsubscribe" button → Goal: prevent subscribers from clicking "Report as spam" 🌐 Who supports it? • Gmail (sometimes displays it even without the header for certain brands) • Apple Mail (since iOS 10) • Microsoft https://t.co/9GmzdaXmHe ��️ The 2 versions 1. List-Unsubscribe (mailto:) → Sends an email to unsubscribe → Essential for Apple Mail users 2. List-Unsubscribe-Post (RFC 8058) → POST request to your server → More secure (bots don't make POST requests) → The future of the standard 🎯 The mistake to avoid Don't implement only the POST version. You'd lose opt-outs from Apple Mail users. 💡 Pro tip: Don't fear the unsubscribe. Subscribers come and go. Trying to lock them down will only harm your reputation. Make list growth part of your strategy. Full article : https://t.co/tPAhTzP3ZH #EmailMarketing #Deliverability #ListUnsubscribe #BestPractices #Emailing

Does your "From" and "Reply-to" need to match in 2026? Not necessarily, but they MUST both be functional. 📧 The 2 recurring questions 1. My "From" isn't routable, but my "Reply-to" is. Is that enough? → No. Both must accept emails. 2. Can my From and Reply-to domains be different? → Yes, but avoid free webmail addresses (Gmail, Yahoo). ⚠️ What's changed • Microsoft now requires sender addresses to exist AND accept mail • "No-reply" addresses are an outdated configuration in 2026 • Spam filters watch for inconsistencies between From and Reply-to 🎯 Pitfalls to avoid • Using a free webmail address (spam signal) • Ignoring replies sent to the From address • Assuming no one will reply to From if a Reply-to exists 💡 Pro tip: People WILL reply to your From address, even with a Reply-to configured. Make sure both lead to a real inbox. Full article https://t.co/rdzYGSO7ST #EmailDeliverability #EmailMarketing #DMARC #BestPractices #Emailing

How much does email marketing really cost in 2026? Spoiler: anywhere from $0 to $10,000+/month. It all depends on your approach. 💸 The 3 options 1. DIY with a platform → $0 to $1,099/month → You handle everything (templates, automation, sends) → Ideal for SMBs and creators 2. Freelancer → $10–200/h or $50–5,000/project → Flexible, focused on specific tasks → Downside: variable availability, no big-picture strategy 3. Agency → $2,500–10,000+/month → Full strategy, analytics, dedicated support → Best for large lists and bigger budgets ⚙️ What drives the price • List size (tiered pricing) • Email volume/month • Automation level • Custom vs ready-made templates • Basic vs premium support 📈 Is email marketing still worth it? In 2024, 47% of marketers doubled their ROI. Projected industry revenue: $15.8 billion in 2026. Unlike social media: no algorithm, direct inbox access. 💡 Pro tip: clean your list regularly - no point paying for inactive contacts.

Why does everyone use 8.8.8.8 as their DNS? This address is Google Public DNS: a free resolver, open to everyone since 2009. Over a trillion queries handled per day. Yes, trillion. But what does it actually do? DNS is the Internet's phonebook. When you type "https://t.co/FHwFKpVdMN", your device asks a DNS server to translate that name into an IP address. By default, your ISP handles this. But you can choose another resolver - like 8.8.8.8. ✅ Advantages of Google DNS 8.8.8.8 • Speed: worldwide anycast infrastructure (your query hits the nearest server) • Reliability: almost never down, Google handles 30% of global DNS traffic • Clean answers: no ad redirects on non-existent domains (unlike some ISPs) • Supports DNSSEC, DNS over HTTPS, DNS over TLS • IPv6 ready: 2001:4860:4860::8888 ⚠️ Drawbacks to know • Privacy: all your queries go through Google (even if logs are limited) • No filtering: 8.8.8.8 blocks neither malware, adult sites, nor phishing • Centralization: relying on a single player for such a critical service is worth questioning 🔄 Alternatives based on your needs 🔒 More privacy → Cloudflare 1.1.1.1 (logs purged in 24h, audited by KPMG) 🛡️ Automatic threat blocking → Quad9 9.9.9.9 (Swiss foundation, filters malware/phishing) 👨‍👩‍👧 Built-in parental control → OpenDNS Family Shield (blocks adult content with zero config) 🚫 Block ads and trackers → AdGuard DNS ⚙️ Full customization → NextDNS (a Pi-hole in the cloud) 🖥️ How to configure 8.8.8.8? On Windows 11: Settings → Network → Ethernet/Wi-Fi → DNS servers → Manual → 8.8.8.8 / 8.8.4.4 On your router: Admin interface (usually 192.168.1.1) → Primary DNS: 8.8.8.8 / Secondary: 8.8.4.4 ➡️ Your whole network benefits automatically On Android: Settings → Private DNS → https://t.co/KvJ5iW9WX3 On iPhone: Wi-Fi → (i) on your network → Configure DNS → Manual → 8.8.8.8 I broke it all down with a comparison chart of public resolvers here 👇 https://t.co/HDMPSR7ori
