Replying to all resumes would be the polite thing to do, but often it simply isn't practical. If a company receives 200 responses for an ad, or experiences a continual deluge of unsolicited resumes, it would spend an inordinate amount of time sending acknowledgments. If you really want a receipt for your resume, send a stamped, self-addressed postcard asking for one. If you make it easy, the human resources department will comply.

Two can live as cheaply as one - if they both have good jobs.

Employers don't consider your resume follow-up a waste of their time. While there will always be potential employers who are firm believers in the "don't call us, we'll call you" approach, most recruiters admire candidates who make an ef fort to follow up on their resumes. Follow-up shows both initiative and persistence, traits good managers love, especially in individuals who are applying for positions with major responsibilities. Don't worry about seeming too enthusiastic. Company representatives enjoy being pursued. It massages their egos and reminds them their company is worth courting.
