Resend's email-best-practices skill guides a coding agent through building email features that reach the inbox and follow the law. It covers SPF, DKIM and DMARC setup, why messages land in spam, bounces and complaints, and keeping a suppression list. It also handles signup capture with double opt-in, consent rules such as CAN-SPAM, GDPR and CASL, webhooks, safe retries and accessible email design. It is written by Resend but the guidance is not tied to one sending service.
Plan a free download that collects emailsThis skill decides what free resource to offer in exchange for an email address and how to get it in front of people. It matches the offer type to the buyer's stage, sets how much to gate it, and covers the landing page and delivery. Writing the asset itself is left to other skills.MarketingLead GenerationContent

Plan and draft a multi-email sequence with timing and branchingAnthropic's email-sequence skill, from its marketing plugin, plans and writes a series of emails for onboarding, lead nurturing, winning back lapsed customers, re-engaging quiet ones or a launch. Each email gets a subject line, preview text, body, call to action and send timing, and the sequence comes with branching rules, exit conditions, benchmark numbers to aim for and a flow diagram. It can work with a connected email or marketing automation tool, or on its own. Its benchmark figures are general guides, not guarantees.MarketingEmail marketingMarketing
Remove AI writing patterns from textThis skill rewrites text that sounds machine-written so it sounds like its author, keeping what the text says. It marks patterns such as staged contrasts, one-line closers, forced triads, overused dashes, inflated claims, and stock AI words, then edits them out. It does not add facts, names, numbers, dates, or quotes the original lacks. It builds on Wikipedia's list of signs of AI writing.MarketingWriting
Write and review interface text: buttons, errors and empty statesAnthropic's ux-copy skill, from its design plugin, writes or critiques the short text inside a product. It covers button and link labels, error messages, empty screens, confirmation dialogs, tooltips, loading states and onboarding lines, following stated principles and patterns for each. Give it the context and any existing copy, and it suggests clearer wording.MarketingDesignWriting
