onetwothreesend

One Two Three Send is a complete newsletter workflow inside WordPress. The plugin uses the Claude API (you supply the key) to draft issues from your site’s content, gives you inline AI editor tools to polish the copy, runs a pre-send audit to catch common mistakes, and sends through Resend or SMTP to subscribers stored in your own database.
<h4>What’s included</h4>
<ul>
<li>AI newsletter generator — Claude drafts a newsletter from your recent posts, site tagline, and a manual description you provide. Tone selector (Friendly / Professional / Casual / Authoritative) and length selector (~200, ~400, ~700 words).</li>
<li>AI editor — select any paragraph and click Rewrite, Shorten, Expand, or Fix grammar. Generate 5 alternative subject lines in one click. Tone check, local spam-word scan.</li>
<li>Pre-send audit — one click runs 10 checks: subject length, body word count, unsubscribe reference, link count, link format, spam triggers, placeholder leaks, readability (Flesch-Kincaid), read time, structural sanity. Each check returns pass / warn / fail with a plain-language explanation.</li>
<li>Scheduling — manual, daily, weekly, fortnightly, monthly. Manual-approval mode emails the admin before any send. Auto-send is opt-in.</li>
<li>Email delivery — Resend (API) or SMTP (any provider).</li>
<li>Subscribers — local database with filtering, CSV export, one-click token-based unsubscribe.</li>
<li>Signup forms — inline form via shortcode <code>[otts_form id="1"]</code>, Gutenberg block, or PHP <code>onetwothreesend_render_form(1)</code>.</li>
<li>Welcome email — automatic, configurable subject and body with <code>{first_name}</code>, <code>{email}</code>, <code>{site_name}</code>, <code>{from_name}</code> placeholders.</li>
<li>Lead magnet delivery — upload a PDF, zip, or any allowed file. New subscribers receive a signed, time-limited download link in the welcome email. Expired links auto-refresh when clicked, no manual resending.</li>
</ul>
<h4>External services</h4>
This plugin calls the following external APIs using credentials you provide. No data is sent to any third party without you entering a key first.
<ul>
<li>Anthropic Claude API (<code>api.anthropic.com</code>) — for drafting and editing newsletters. You provide the API key in Settings → AI. Terms: https://www.anthropic.com/legal/consumer-terms. Privacy: https://www.anthropic.com/legal/privacy.</li>
<li>Resend (<code>api.resend.com</code>) — optional, for email delivery. You provide the API key in Settings → Email Provider if you choose Resend. Terms: https://resend.com/legal/terms-of-service. Privacy: https://resend.com/legal/privacy-policy.</li>
</ul>
The plugin itself does not phone home. It does not contact onetwothreesend.com or any server other than the ones you explicitly configure above.
<h4>Companion plugin</h4>
A companion plugin (One Two Three Send Pro, distributed separately) can extend this with Stripe paywalls, Mailchimp / MailerLite / Brevo / ConvertKit providers, popup and slide-in forms, and more. One Two Three Send is fully functional on its own — the companion plugin is optional. <a href="https://onetwothreesend.com/pricing/" rel="nofollow ugc">Pricing and details</a>.
