Zoho ZeptoMail

I just started using ZeptoMail. I don't know how it will help me in long-term but the plugin is super, the email delivery is great and the pricing is the best in the market.

I'll be literally spending only ₹25 per month for those painless transaction emails.

Once again, thank you! Please keep the good work.

Easy, cheap and fast!

<p>Send transactional and marketing emails from your WordPress site using the <a href="https://lettr.com" rel="nofollow ugc">Lettr</a> email API. Lettr replaces the default WordPress email system with a reliable, developer-friendly API that delivers emails to inboxes — not spam folders.</p>
<h4>Why Lettr?</h4>
<ul>
<li><strong>Reliable email delivery</strong> — Built on battle-tested infrastructure with SPF, DKIM, and DMARC authentication out of the box.</li>
<li><strong>Simple setup</strong> — Connect your WordPress site with a single API key. No SMTP configuration needed.</li>
<li><strong>Transactional email at scale</strong> — Send password resets, order confirmations, notifications, and more through the Lettr email API.</li>
<li><strong>Real-time tracking</strong> — Monitor opens, clicks, bounces, and deliverability from the Lettr dashboard.</li>
<li><strong>Templates & personalization</strong> — Use the Lettr drag-and-drop editor and merge tags for dynamic content.</li>
<li><strong>Developer-first</strong> — RESTful API, detailed documentation, and SDKs for PHP, Node.js, Python, Go, Rust, Java, and Laravel.</li>
</ul>
<h4>How it works</h4>
<p>This plugin overrides the default WordPress <code>wp_mail()</code> function and routes all outgoing emails through the Lettr API. This means every email your site sends — including emails from WooCommerce, contact form plugins, and any other plugin — is delivered through Lettr automatically.</p>

</ul>
<h3>External services</h3>
<p>This plugin connects to the Lettr API at <code>app.lettr.com</code> to deliver email on behalf of your WordPress site. Each time <code>wp_mail()</code> is invoked, the plugin sends the following data to Lettr over HTTPS so that Lettr can process and deliver the message:</p>
<ul>
<li>The configured sender email address and name</li>
<li>Recipient, CC, BCC, and Reply-To addresses</li>
<li>The email subject, HTML and/or plain text body, and any attachments</li>
<li>Any custom email headers, tags, or metadata supplied by the calling code</li>
<li>Your Lettr API key (sent as a Bearer token in the <code>Authorization</code> header for authentication)</li>
</ul>
<p>The plugin also calls <code>app.lettr.com/api/auth/check</code> to validate the API key when you save it on the settings screen.</p>
<p>This service is provided by Lettr. By using this plugin you agree to Lettr’s terms and acknowledge their privacy practices:</p>
