Daily Morning Briefing — October 20, 2026 Edition: Email Marketing & Automation

Masthead deck. Klaviyo had the loudest day in email: the Boston B2C CRM platform was named Official B2C CRM Partner of the Atlassian Williams F1 Team from 2027, and its management interface went live in Japanese for the Shopify merchant market. The counterweight is a fast-spreading Japanese-language investigation into phishing mail that passes SPF, DKIM and DMARC and shows a BIMI brand logo — proof that authentication is not the same thing as trust.

3. A DKIM-replay phishing wave is dominating Japanese email-security discussion: a Rakuten Card–branded message delivered to NTT docomo passed SPF, DKIM and DMARC and displayed a BIMI logo. (@takehora, 2026-10-19 16:21 UTC, @Hentaineko RT wave, 2026-10-20 04:00 UTC)
4. Omnisend is being framed as eating Klaviyo's SMB share, with one 1,477-follower commerce analyst arguing Klaviyo is not defending the small-merchant tier it is losing. (@elliotkovac28, 2026-10-20 00:36 UTC)
