Strong Tamil Messaging Preference<\/h3>\n<p><span style=\"font-weight: 400;\">Many customers still prefer short Tamil or Tamil-English hybrid SMS, especially in retail, healthcare, education, and local services. <\/span><span style=\"font-weight: 400;\">Short, localised messages get higher open and click rates.<\/span><\/p>\n<h3>2. High Mobile Penetration<\/h3>\n<p><span style=\"font-weight: 400;\">With one of India\u2019s highest smartphone adoption rates, Chennai\u2019s SMS engagement remains consistent across urban and suburban zones.<\/span><\/p>\n<h3>3.
