首先要确认展会邀约对象：与自己成交过订单的，还包括之前曾经与你联系过、询问过相关产品的意向客户。
其次，邀请函应该注意哪些方面呢？
01、不要千篇一律
有些工作人员会上网找一些范文，全篇照抄，然后只改动一下名字和展会的地址，就完成了任务，其实这样会显得没有诚意。客户不仅仅是只跟一家公司做生意，邀请函可不止收到一封，类似的范文他可能已经见过几百遍了，这样的邀请函实在缺乏专业度和诚意度。如果能针对客户写一些诚意十足的文字，在文中对客户致以问候，尤其是能在文中提一下跟该客户上次的谈话细节，更能加深对方的印象，这样才是一份好的邀请函。
02、附上交通路线
在邀请函中附上交通路线。尽管客户可能已经参观过很多次这样的展览了，他对展馆的地理位置十分的熟悉，但是如果参展商能在邀请函中附上交通路线，则会显得亲切细心。比如像琶洲展馆，一到广交会，周围的交通就十分拥堵，如果客户是开车来的话，可能会在路上耽搁不少的时间。若参展商在信函中告知客户“为了防止出现塞车，耽搁您的时间，建议您可将车停在酒店，选择地铁前往，在琶洲或者新港东站下车即可”，同时附上地铁线路图，这样的邀请函相信能给客户留下很好的印象。
02、邀请时间有讲究
参展商在某个地区可能有不止一个代理商，那么在邀请这些客户来参观展览的时候，邀请时间就有讲究了，应该尽量将他们的参观时段错开。因为同一个地区的代理商，可能就是直接的竞争对手，为了避免引起尴尬，最好是一个安排在上午会面，另外一个安排在下午。
03、附上展馆平面图
邀请函里附上展馆平面图，可以让客户更容易地找到展位。主办方会提供展馆平面图，上主办方的官网下载电子版，自己打印或者拿到纸质的图样进行复印，再附在邀请函里。
04、告之天气情况
参观展览的客户来自全世界各地，他们并不熟悉展览所在地的情况。比如说广交会，广州的天气连第一次来的北方人都觉得不习惯，参展商如果能在邀请函里将未来几天详细的天气情况告诉客户，并附上生活上该注意的细节，则显得细心体贴。
附上几封可作参考的邀请函：
