While auto correct is a valuable tool, it has some limitations: 1. Contextual Errors: Auto correct may not always understand the context of your message, leading to incorrect suggestions. 2. Technical Terms: It may struggle with industry-specific jargon or technical terms, flagging them as errors. 3. Over-Reliance: Relying solely on auto correct can lead to complacency, where marketers might not proofread their emails thoroughly.
