I am a Ph.D. student in pure mathematics. Recently, I received a very positive review of one of my articles from a good (or at least average) journal. After a minor revision, I sent back the revised paper to the editor. After getting no confirmation after 6 days, I sent him another follow-up email saying "Please confirm upon receipt of the revised paper". But still, four days passed, and I got no reply. So I am confused about whether he really received the revised paper or not.
Let me tell you that the journal only follows email communications; there is no online submission portal. We (me and the editor) have used the same email message from submission to status inquiry to revision; that is, I submitted the paper and he received it by replying to my message, then I queried the status of the paper by replying to the same email message, and he answered the status, and so on. So far, we've communicated about 15–20 times over the same email follow-up. Is there any limit to replies in Gmail? Or, simply, he is very busy, so he received it but forgot to reply both times? It has been 10 days since I sent the revised paper, and 4 days ago I sent a follow-up message to know if he received it.
Would it be annoying to inquire in a separate message (of the same email address) if he received the revised paper? Or, should I wait for the final decision, assuming that he has received my revised paper?
I appreciate your guidance
