Clockwork SMS Notfications

Description

Free: Send your subscribers SMS messages when you publish a new post via free email to SMS gateways. Many mobile providers throughout the world provide free email to SMS gateways, which this plugin uses to send the SMS notifications. Because the gateways are free, some mobile providers do not prioritise their maintenance or publicise their existence, this plugin uses a central list of known working gateways which is provided by SMS service provider Clockwork as a service to the community.

Paid: Send your subscribers SMS messages when you publish a new post through Clockwork SMS. Clockwork is a paid SMS gateway. We charge 5p per SMS in the UK, and deliver to over 900 networks in over 200 countries worldwide. It’s free to upgrade the plugin – you only pay for the SMS messages you send to your subscribers. This also simplifies the widget so that instead of having to choose their country and network, your visitors just have to enter their phone number – and we do the rest.

Nobody is receiving notifications!

Check that the email service from your WordPress site is working. One way to do this is to log out then try using the “Lost your password?” link; if you don’t receive the email, then you may have a problem with the ability for WordPress to send email.

The most common email sending problem with WordPress is that the default “from” email address is “wordpress@[your domain here]”, which is an address that often doesn’t exist. Here are a few things which you could try to fix the problem:

  • Can you create the email address “wordpress@[your domain here]”? In that case, create it.
  • Change the “from” address to one which you can create, or which already exists, using a plugin. This plugin might help: WP Mail SMTP (this plugin does more than allow you to change the “from” address, but first just restrict yourself to that).
  • Also using the WP Mail SMTP, you could try changing your email sending service to the one which comes with your email host (contact them for SMTP details).

If all the above fail, and your WordPress site is not sending any email, you could try hitting the forums where there’s a bunch of super helpful WordPress people, just like you. Make sure you explain your problem clearly and detail what you’ve tried (without including any login information).

If your WordPress site is sending the forgotten password email, but your SMS notifications aren’t arriving, please email us.

We have not been getting automatic SMS messages when a new post is added to our website for about 3-4 months now. It clearly states that it has not been tested for this version, but since it is the latest WP version, maybe someone will get it working again soon. I cannot find a good alternative,
