Step by step: Direct-to-Voicemail Campaigns

Direct-to-Voicemail campaigns are one of the simplest campaign options offered on SENDR. Creating such a campaign only requires three steps and a few minutes.

Direct-to-Voicemail campaigns use a specific protocol to avoid ringing your prospect’s phone. It can be particularly useful in certain situations, such as for debt collection campaigns.

Step 1 - Creation

In this step, you will set up the name of the campaign, its nature, the recipient choice as well as the caller identity, and finally its type.


  • First, choose a campaign name. Try to choose a campaign name that you will easily recognize later for reporting purposes. You might decide to choose the motive, audience or date, such as ‘Summer Sale promotion 28/08/2017’.
  • Next, choose a campaign type. Only Straight-to-Voicemail campaigns will be covered in this tutorial. For other campaign types, please check the relevant tutorials.
  • Next, choose the nature of your campaign: marketing or alerting. If you’re not sure which category your campaign falls under, refer to our dedicated articles.
  • Next, choose a sender for the campaign. This is the number or name that will be shown as the sender on your recipients’ phones. 
    For a 
    voice campaign, the caller can either be “BLOCKED” (unknown number) or any DID you ownCheck this article to learn more about what types of number are available and how to buy them.
  • Finally, choose an address book of phone numbers to send your campaign to. If you would like to exclude certain people - for example, those who have unsubscribed - you may do so by choosing the appropriate blacklist.

Step 2 - Message

For a direct-to-voicemail campaign, you need to set up a/several media(s) that will be played to your prospects. You can upload a pre-recorded file, record it with your phone or use Text-to-Speech (TTS) to read a prompt you will write. With TTS, you can also use any variables included in the address book, such as your prospect’s name or city; TTS let you personalize you campaign using any data you might have on your prospect. If you need more information on medias, please check the dedicated article.


Campaign Testing

Once the campaign message is set up, the “Test Campaign” button at the top right of the screen will be highlighted in blue. It will allow you to test your campaign on the number of your choice to ensure everything is as you would like it to be.

We strongly encourage you to test your campaigns before starting them.

Step 3 - Options

For Direct-to-Voicemail campaigns, two options are available: scheduling and SMS/email completion report.

Scheduling options


With the scheduling options, you can choose the days and a time window for you campaign execution. You can also set up a daily pause, to avoid calling people during their lunchtime for instance.

The default time zone is set to Paris. If you are using SENDR to reach another country, don’t forget to change the time zone accordingly.

Please keep in mind that marketing campaigns are subject to restrictions depending on the country the campaign takes place in  (nature of the campaign is set up at step 1). In France, marketing messages will be sent only during weekdays between 9 AM and 7 PM.

Marketing traffic restrictions vary per country, we encourage you to check the legal framework of the country you wish to operate in to ensure full compliance with the law. Alerting traffic is not subject to restriction.

Reporting options


If you so choose, you can receive a completion report for the campaigns on up to 5 phone numbers or email addresses. Once the campaign is completed, you will receive a message on your specified phone numbers and email addresses which include:

  • Campaign name
  • Start and end time of the campaign
  • Address book used
  • Total cost of the campaign

The full campaign report is accessible directly through the interface. Check our dedicated CDR article if you need more information.

Once you are done, click save. You will be taken back to the campaign’s dashboard where your newest campaign will be on top. Don’t forget to click the corresponding start button to launch the campaign once you double checked everything.
