Annual plans from Drip are designed to save you money. Drip works on a credit system, so when you purchase an annual plan, you get two months of free bonus credits added to your account. When your subscriber count grows, and you move up a plan, your credits get used more quickly at your new rate. If some of your contacts unsubscribe, or you decide to prune your list - we’ll simply move you move down a plan, and you’ll continue to use your credit balance a bit slower.
Whenever your account runs out of credits, we’ll automatically extend your membership on an annual basis, and once again, add two new months of free bonus credits at your updated plan level.
