SendinBlue is a great choice for small businesses and individual marketers as well as bloggers. They have a free plan like MailChimp and the free option is much better as compared to the one offered by MailChimp.
If you go for the free plan of MailChimp, you will have a cap of 2000 subscribers after that you will need to upgrade your plan to any of the paid options. However, SendinBlue gives you the option to host a list of unlimited subscribers with a daily email limit of 300, which means you can send 9,000 emails per month free.
SendinBlue’s paid plans start at $25 and you can send up to 40,000 emails per month.
