See why Constant Contact users switch to Sendinblue

“As we expanded the number of contacts, Constant Contact pricing became a problem. We are a non profit alumni association. The pricing Sendinblue offered was our reason for selection.”

Joe Davis

“I had been using Constant Contact for years! Most of the newsletters ended up in spam or promotions tabs for people who actually wanted to receive them. [...] I googled and found Sendinblue. It was easy and the info ended up in their inbox! I will never turn back. #gamechanger”

Aerial Tam

“When comparing the setup and ease of use for both products, plus how well it suits our needs, Sendinblue was the clear choice.”
