If you receive an e-Tourist Visa then this will be e-mailed to you. You are expected to print it out, carry it with you, and show it at airline check-in and at immigration. No visa sticker will be placed in your passport.
On arrival in India you will get an entry stamp, the same as everyone else.
Note that the e-TV only grants a single entry good for 30 days stay. If you need another entry, you can apply for another e-TV later; if you need a longer duration or multiple entries, consider applying for a regular visa instead.
