SuiteMkt3k brings a modern style admin to WooCommerce sites and adds the marketing automation features online stores actually need:
<ul>
<li>Coupon campaigns with scheduling and calendar view.</li>
<li>Two display formats: top banner or popup, plus two coupon formats (classic and opt-in with a 2-step popup that captures Name, Email and Birth date).</li>
<li>Newsletter editor based on email-safe templates (no raw HTML required) with batched delivery, open tracking pixel and click redirector.</li>
<li>Subscription form builder via shortcode.</li>
<li>Abandoned cart capture from the checkout, manual or automatic recovery emails (with optional auto-generated WooCommerce discount coupon and unique link to restore the cart).</li>
<li>Full subscribers manager (search, filters, CSV export, edit/delete modals) with GDPR-compliant unsubscribe links.</li>
<li>Statistics dashboard powered by Chart.js (impressions, clicks, opens, conversions, revenue).</li>
<li>Own SMTP that only overrides for plugin emails (X-SuiteMkt3k header) so it never conflicts with general SMTP plugins.</li>
<li>Language selector (Spanish default + English), per-user override.</li>
<li>AES-256-GCM encryption for SMTP password, rate limiting on public endpoints, capability-based access control and prepared SQL everywhere.</li>

PW WooCommerce Copy Coupon

Does what it says!

You saved me about 10 clicks and 1 minute each for 90 coupons I had to setup. That is worth a 5 star review.

Did what it says it does.
Works out of the box.

Once installed, on the list of all coupons, you'll see a third option when you hover a single coupon, besides Edit and Trash there will be a Copy action.
Once copied, the new coupon will be opened so you can immediately edit the title of the coupon.

I'm a developer and have inspected the code which is neatly organized and I didn't encounter any errors/issues while running the plugin.

Excellent and simple

Simply adds a Copy button to WooCommerce coupons to make it easier to create new coupons!
