Plug WiseSender into the tools you use

A WordPress plugin, webhooks and HTTP steps for no-code tools, and a plain REST API for everything else. All of them use the same account, lists and credits.

WordPress plugin

One plugin for WordPress and WooCommerce

Install it, paste your keys, and your site gets three jobs done without writing a line of code.

  • Reliable email. Password resets, WooCommerce receipts and form notifications go out through WiseSender from your domain, with a fallback if anything fails
  • No fake signups. Emails on registration, WooCommerce checkout, Contact Form 7 and comments are checked, and typos or throwaway inboxes are refused with a "Did you mean...?" hint
  • A growing list. New users, and customers who tick a box at checkout, join one of your WiseSender lists

Automations without a special app

Every automation tool can catch a webhook and make an HTTP request. That's all you need to connect WiseSender to thousands of apps.

Triggers

When something happens in WiseSender, start a workflow. Paste a "Catch Hook" or "Webhook" URL into your dashboard.

  • contact.subscribed and contact.unsubscribed
  • list.verified when an uploaded list is done
  • campaign.finished when a campaign is sent or stops
  • Delivery events like delivered and bounced

Actions

Do something in WiseSender from any app, with an HTTP step and your key in the header.

  • Add a new customer or lead to a list
  • Verify an email before it reaches your CRM
  • Send an email from a template
  • Unsubscribe someone who opted out elsewhere
Example: add a Typeform or Shopify signup to a list
POST https://wisesender.com/v1/lists/12/contacts
X-API-Key: ws_live_...

{ "email": "[email protected]", "name": "Ann Lee", "verify": true }

# 201 Created
{ "email": "[email protected]", "status": "subscribed", "created": true }
