Rephrase this:

The evidence is not sufficient enough; the claim states that there are many ways. When the evidence provided only one sentence to convince people. Mail isn't the most secure or efficient either. Therefore, this is not convincing because there is too little evidence.

The evidence presented is insufficient to support the claim that there are multiple effective methods. Only one sentence was provided to convince readers, making the argument unconvincing. Additionally, email is not considered the most secure or efficient method. Therefore, the lack of evidence provided makes the argument weak.

1 to 2 sentences

The lack of sufficient evidence and reliance on only one sentence to support the claim weaken its persuasiveness. Additionally, the inefficiency and lack of security in email further hinder the argument's credibility.
