群发短信对教育机构来讲虽然是个不错的招生工具,但怎么使用决定着生源转化效率,如果是为了单纯的发短信而发短信效率当然不好,那么如何正确使用招生群发短信呢?技巧才是关键!

　　教育短信发送较多的就是招生群发短信内容,而运营商对教育行业内容审核一般比较严格,需要短信公司特殊的教育短信通道配合才能完成大批量群发任务.

　一般招生群发短信效率比较好的用户是这样发的:

　1、过滤无价值的推广内容

　　招生短信要明确发送目标和目的,短信内容尽量短小简洁,这也是为什么一条短信建议尽量控制在70字以内的原因,切忌长篇大论,生怕招生信息说不完一样,反而容易引起用户方案或投诉,影响效率不说,得不偿失!

　　2、招生群发短信请控制发送频率

　　教育企业可以针对招生推广目标制定相应的发送时间表,在短信平台设置发送里可以提前设置发送时间,比如在高考冲刺前推送考考补习课程、小升初推送相关补习质量等.一般建议1天发送1次即可,群发短信时间,建议根据自身客户阅读习惯来自行安排.

　3、挑选比较感兴趣的话题

　　招生也不一定非得发送招生内容,招生群发短信现在比较流行的是采用热点话题,委婉的引入课程营销,”露骨式”的营销方式在遍地营销短信的时代已经达不到吸引用户的目的了,所以只有充足的了解师生需求,配合话题热点才能吸引更多流量.

　　总结：使用招生群发短信技巧只是其一,稳定的平台通道是硬件基础,二者相辅相成才能取得期望的生源转化效率.
