thanks for submitting your paper to XXXXX Journal. It is an explicit and interesting analysis of a natural problem. However, in my opinion, it does not reach the level of XXXXX Journal. I therefore have decided not to pursue the evaluation process in order not to delay the publication of your paper elsewhere.
Please don’t take it too bad, XXXXX Journal receive a lot of very very strong submissions in every aspect of mathematics and we publish only 700 pages per year, so we have to make some hard choices.
Best regards, XXXXX (Editor-in-chief)
Dear Professor XXXXX,
The XXXXX Journal of XXXXX recently received a very large number of submissions. We are also attempting to reduce our publication backlog. Consequently, the editors are unable to consider every manuscript for further review. So we regret to inform you that we will not be able to publish your manuscript.
We hope that you will submit your paper to a more specialized journal where your work may be more fully appreciated.

Are both of these are just boiler plate or anything to salvage from them. I must say both are really top journals in mathematics.
