Score Developing
ClarityDeveloping
Strengths: The email clearly states the delay and the reason in the opening paragraphs.
To improve: The revised timeline is presented in a run-on sentence that is hard to follow.; The hedging language in the first paragraph makes the message less direct and clear.
ProfessionalismCompetent
Strengths: Uses a proper salutation and sign-off.; Includes a clear subject line and appropriate closing.
To improve: The signature block is incomplete (missing full name and title).; The phrase 'some small delay' downplays the significance of a two-week delay.
ToneCompetent
Strengths: Apologizes sincerely and expresses appreciation for the client's understanding.
To improve: The excessive hedging ('I think maybe it could be possible') weakens the tone of confidence and accountability.; The closing could be more direct and professional.
GrammarDeveloping
Strengths: Generally understandable grammar with some correct complex sentences.
To improve: Several subject-verb agreement errors (e.g., 'system need', 'engineer are').; Missing articles and incorrect prepositions are present.; A run-on sentence in the timeline paragraph needs correction.
Feedback Summary

This email communicates the essential information about the delay and revised timeline, and the tone is appropriately apologetic and appreciative. The main areas to work on are grammar (subject-verb agreement, articles, prepositions) and sentence structure (run-on sentences, word order). The hedging language could be reduced to make the message more direct and confident. With some revision, this email will be clear and professional.

Native Language Analysis

Native language analysis — Japanese

We found 7 error instances across 4 categories that match known patterns for Japanese speakers. These are not deficiencies — they are predictable challenges caused by differences between Japanese and English. Recognizing them is the first step to overcoming them.

You are a senior developer at BrightCode Solutions. Your team has been building a custom inventory management system for a retail client, Apex Retail Group. Due to unexpected technical challenges with third-party API integration, the project will be delayed by two weeks beyond the originally agreed deadline. Write an email to your main contact, Lisa Torres (VP of Operations at Apex), informing her of the delay, explaining the reason, presenting a revised timeline, and reassuring her about the quality of the final product.

Dear Ms. Torres, Thank you very much for your continuous support to our project. I am writing to you because I think maybe it could be possible that there will be some small delay about the inventory management system which we are developing for your company. As you know, the system need to connect with the third-party API of your warehouse partner. During the integration test of last week, our team found that the documentation of this API was not correct, and the data format is different from what was described in it. Because of this, is necessary for us to rewrite some part of the connection module. We deeply apologize for this inconvenience. The revised timeline I would like to explain as follows. The integration will be completed by 15 March, the user acceptance test we will start on 18 March, and the final delivery will be 29 March. This is approximately two week later than our original schedule. I would like to say that the quality of the final product will not be affected. Actually, our engineer are testing every function more carefully than before, and I believe maybe this will make the system more stable in the long term. If you have any question, please do not hesitate to contact me at any time. I am very sorry again for this matter, and I appreciate your kind understanding. Best regards, Senior Developer BrightCode Solutions
