A: Hi! Thanks for your question. You are right but it refers to features developed by Acumbamail. Social Media is a feature developed by a third party so that's why it is not included.
Anyway, if you want to use this feature, send us an email to support@acumbamail.com and they will tell you which is the price if you want to include it as an addon.
I hope it helps.
Best,
Alicia
