Call it happenstance or call it predestined, either way, I am one happy user of SendinBlue and it was all because of a simple Google search and an initial free plan that was beyond generous. SendinBlue has stood up the test of deliverability and continuity. The onboarding, even for a free plan, was simple yet effective. The initial import of contacts and subsequent email campaign was placed on a hold while SendinBlue verified with me how I obtained the contacts and if I had permission to send to these addresses. It was a simple questionnaire and quick phone call and the list was approved and my account marked as safe to send. The process was quick and they scored major points with me in the way they protect their sending IP. This level of scrutiny signaled one important point to make: your emails will end up in the inbox, not in a junk folder. This can equate to increases in sales and thus revenue. Other email marketing programs with less scrutiny will also deliver to fewer inboxes. For brand protection and promotion, there is not a single better solution, in my opinion, than SIB. We use it for our email campaigns and have placed clients with SIB.
