In Savvy emails are unlimited and free, but for all of your messaging you can also choose to send via SMS if you want to.
SMS should be kept short as 1 SMS credit is used for a message of 160 characters or fewer and 2 credits for 160+.
Every plan has an SMS allocation, if you need more SMS, that's fine, you can review your usage and purchase more SMS by clicking on the speech bubble top right in your Savvy.
SMS bundle purchases have no time limit and will stay on your account if you need them, perfect if you want to make use of the large bundle discounts.
