Best for Small Business Marketing I am going to go for addons as well and gonna integrate SMS services also in my account for sure

As a consultant I have helped clients to grab it on a monthly plan to send more than 100K emails per month but did not use it for ourselves till now, so now is a time for us.

why we like it
Did you know, Sendinblue’s email marketing platform was developed in response to one of the biggest challenges faced by small-to-medium businesses: automating email marketing on a budget.

Everything, from its comprehensive feature set (which includes a CRM, marketing automation, transactional emails, SMS, landing pages, and Facebook ads), to its extremely competitive pricing, shows that Sendinblue is serious about becoming a major player in this historically underserved market. What I liked is that it has an email plugin for WordPress so blessings for our WP and Woo sites.
For me, it's as good as a tier 1 enterprise tool for email marketing and processing services.

Buy it, I see not much time is left when I am posting this review
