When you have something to say to your subscribers, creating and sending a campaign is the way to go.

Creating a campaign is a multi-step process, very easy and intuitive.
You will have to provide various informations but most of what you have to provide is already populated based on your lists and on your company details, you will have to do just small edits.
Basically, you will have to name your campaign, choose a list of subscribers and a segment from that list if applicable, select a template for this campaign and confirm the sending.

Campaign tags When sending a campaign, there is a high number of tags and filters available for you to use in the content of your campaign.
You can see all of them when you are at the Template step in campaign creation.

Pausing campaigns If you are doing a huge announcement and you expect a high number of subscribers reaching your site at the same time, you can pause the sending of a campaign in order to avoid your site getting hammered.
You can resume sending your campaign at any point when you think it is safe to continue sending.

Campaign sent, now what? Okay, so your campaign has been sent and now you wonder what to do?
Well, in this case, all you can do is to visit the statistics area of the campaign and keep an eye on what is happening.
