Voxpress integrates your wordpress site with the Ubivox newsletter service. Subscribe, unsubscribe, archive lists and much more.
The Voxpress is free, but requires an active Ubivox account with API access which is a paid service.
The Voxpress plugin is supported just as yor Ubivox account, through the regular Ubivox support channels.
The Voxpress support is charged the same way as the support for your Ubivox account. E-mail support is free, but phone support requires a payed support contract.
We might provide consultancy install service of the plugin, depending on how complex the site is and time available. Please contact our support to discuss options and possibilities.
