Yes, you can! And it has many advantages.
When you upgrade your account and pay by credit card, your account will be active immediately so you can launch your survey and start collecting responses straight away.
When you order new packs of emails or respondents or when you pay for extra services, your credit card details will be filled out automatically. You’ll only need to verify and confirm your payment.
You can update and delete your credit card details, or you can add a new card at any given moment.
