Emailens MCP tools 9
preview_emailFull email compatibility preview, transforms HTML for 21 email clients (Gmail, Outlook, Apple Mail, Yahoo, Samsung, Thunderbird, HEY, Proton Mail, AOL, Fastmail, Superhuman), analyzes CSS, generates scores, simulates dark mode, checks inbox preview and email size.analyze_emailQuick CSS compatibility analysis, returns per-client scores and one finding per problem, listing the clients it affects. For HTML input each finding carries loc (line, column, offset) and alsoAtLines, so you can edit the exact source. Narrow with clients, or pass detail:'full' for the per-client breakdown with fix snippets. Use audit_email for a full quality report (spam, links, a11y, images, etc.).audit_emailComprehensive email quality audit: CSS compatibility, spam scoring, link validation, accessibility, images, inbox preview, size (Gmail clipping), template variables, content overflow, visual fallbacks, dark-mode and mobile text contrast, design consistency, structural faults in Outlook-only VML (which lives inside conditional comments and is invisible to every other check), and style survival: CSS a client parses correctly and then discards, such as a stylesheet past Gmail's 16 KB ceiling or every rule after a `}}`, which no support matrix can express. For HTML input, findings tied to a specific element carry loc (line, column, offset) so you can edit the exact source. Compatibility is collapsed to one finding per problem listing the clients it affects; pass detail:'full' for the per-client breakdown with fix snippets. Use skip to omit checks and clients to narrow which clients are reported.fix_emailGenerate a structured fix prompt for email compatibility issues. Returns markdown with the original code, detected issues (CSS or structural), fix snippets, and format-specific instructions. Use after preview_email or analyze_email.list_clientsList every supported email client with IDs, names, engines, and dark mode support.diff_emailsCompare two email HTML versions, shows score changes, fixed issues, and newly introduced issues per client. Use after making fixes to verify improvements.check_deliverabilityCheck email deliverability for a domain: SPF, DKIM, DMARC, MX, and BIMI records. Returns a score (0-100) and actionable issues.
