Free tools for people who send email and SMS

Most of what decides whether a message lands happens before you press send. The DNS records are right or they aren't. The subject line clears the spam filters or it doesn't. The message is one SMS segment or it is three, and you find out on the invoice. These tools answer those questions now, on real data — the DNS checker runs live lookups against your nameservers, and the pricing and ROI calculators use the same plan bands and regional SMS rates we actually bill on. Nothing is stored and nothing is emailed to you, so they are worth using whether or not you ever send a message through WeZend.
