Rathnamma (69), one half of the social media couple popularly known as ‘Achamass,’ has died in Kollam, Kerala.

According to a report by Mathrubhumi, Rathnamma was the wife of Thulaseedharan, a resident of Rajeev Bhavan in Kalayanad, Punalur.

The duo became known through their Instagram page @_acha_mass, where short clips of their daily interactions, light humour and affectionate moments struck a chord with viewers. Their videos often travelled beyond Instagram, getting widely shared across platforms.

Health issues led to pause in social media activity
As per Mathrubhumi, the couple had not been active on social media for some time due to health-related concerns. Thulaseedharan had suffered a stroke and had been undergoing treatment in hospital for nearly 20 days, which led to a pause in their regular content creation.
Even after their reduced activity, older videos from their page continued to circulate online, keeping their presence alive among followers. Many users often reshared these clips, describing the couple as warm and comforting to watch because of their easy chemistry and gentle humour.
Family managing their social media account
The couple’s Instagram account was being managed by their grandsons, Amal Raj and Akhil Raj, who handled posting and updates on their behalf, as mentioned in Mathrubhumi. Their daughter-in-law is Bindu.
