Are the products offered by the same company and common brand. Is it okay to let users know that by sending from firstname.lastname@example.org, email@example.com - technically you can use different “segments” for different products and lists but in my case this would have made things hectic and unorganized for me.
I deploy a similar model by the way, I use several mautic installation for several independent brands/websites. And inside some of these installation, I use segments and lists for different offerings. For example “Marketing Professionals” are getting communication other than “C-Level Execs” including being communicated to about different products and offerings. but all under the same brand/company/url.
The agency model solves your problem. Despite that you don’t run an agency, but actually as someone with multiple brands and a central management you are an agency for your products. The features there would work very well for you, if you are managing different brands.
Currently there is no sendy integration, I thought about it and it seemed counterproductive as managing contacts “subscribe”, “unsubscribe” clicks is core features of both and deep integration wouldn’t make sense mautic is on its way to do everything that sendy can do. I also used to have a single sendy installation and used it for several “brands” but the logic so far for mautic is different.
I split sendy “brands” into separate mautic installations.
P.S. the only major issue missing now, is that sendy uses Amazon API which makes sending much faster, mautic is on its way to do the same, but currently sending takes much more time.
