A recorded face builds trust faster than text, and that is genuinely true. It is also an extra step between the email and the point.
The trade is worth making when the offer is hard to explain in three sentences, and not worth making when it is not. A one line ask does not need a production.
And the personalised backdrop trick is recognised now. Your prospect’s own website behind your head reads as automation, which is the opposite of the intended effect.
How we do it
We do not send video. The message is short enough that it does not need one, and every extra hop is another thing between the reader and the reply.
