If I sent a submission to a publisher and they liked my work and wanted the whole manuscript, is it necessary for me to send a self addressed envelope? Wouldn't they just contact me themselves? This is sent in mind that I don't want my submission back.If you clearly mark your cover letter (eg, CAPS and bold. Don't assume that someone's going to read the cover letter) with the fact that you have omitted a SASE because you don't want your manuscript back and do not expect a response if the answer is no, then publishers should be ok with that.
Don't most publishers have a certain time limit for response?Not if you don't include an SASE and the answer is no.
If the answer is yes, well, it varies a great deal by publisher how long it might take them to respond. Check submission guidelines to see if they say how long to expect to wait.
Couldn't I just wait until the time limit has past and assume that they were not interested if I haven't heard from them. I am asking as I haven't figured out how to get stamps from the country that I want to send to, to put on a self addressed envelope.Yes, you could. That's a pretty healthy attitude, too, which is why publishers will not assume you have that attitude unless you're very clear about it. Some submitters are wringing their hands from the moment they drop something in the mailbox, and if they don't hear from a publisher in the time they think they should, they'll be on the phone to them. Which we do NOT want.
