Devrel Newsletter Deliverability
Keeps a developer newsletter's opt-in email in the inbox - SPF, DKIM and DMARC alignment, the sending subdomain, Gmail, Yahoo and Outlook bulk-sender rules, one-click List-Unsubscribe headers, warm-up after a platform move or months of silence, bounce codes, corporate mail gateways, spam-folder diagnosis. Use whenever someone says their newsletter or digest lands in spam, asks which DNS records their newsletter tool needs, is switching newsletter platforms, wants to mail a long-quiet list, sees 5.7.x rejections, or asks about DMARC or a dedicated IP for newsletter mail - even if they only say 'nobody gets our emails'. Not cold outbound, transactional mail or receiver-side filtering. Do NOT use for list growth or signup consent - use samber/developer-relations-skills@devrel-newsletter-growth.
