Requesting all records from a Custom Object - Velocity Script

We are trying to come up with a Velocity Script to display all records from a Custom Object.

We have Subscribers (leads) with 1, 2, 3 or more  Beneficiaries in a Custom Object. Our email message should look like this:

Dear <Subscriber Name> .
Here is the info about your Beneficiaries:

Beneficiary 1 Name
Beneficiary 1 Plan #

Beneficiary 2 Name
Beneficiary 2 Plan #

Beneficiary 3 Name
Beneficiary 3 Plan #

I tried to use the following script for this:

${beneficiary_cList.get(0).beneficiaryFirstName}
${beneficiary_cList.get(0).beneficiaryPlanNumber}

${beneficiary_cList.get(1).beneficiaryFirstName}
${beneficiary_cList.get(1).beneficiaryPlanNumber}

${beneficiary_cList.get(2).beneficiaryFirstName}
${beneficiary_cList.get(2).beneficiaryPlanNumber}

However, if a Subscriber has less than 3 records in a Beneficiary Custom Object, this script would return an error and the email won't be delivered.

Is there another solution for this?
