How to Get an Exchange Rate Alert by Email
Updated September 2, 2026
Sending money home, paying a tuition bill abroad, saving for a trip: the exchange rate decides how much you actually pay, and it moves every day. Watching it means opening a converter and remembering the number you were hoping for.
An email does the remembering for you — the rate every morning, or a single note the day it crosses your line. Here's how people set that up.
The do-it-yourself options
Transfer apps like Wise, XE or Revolut offer rate alerts. They work well — for the pairs they support, on the phone they're installed on, and with a nudge toward their own transfer when the alert fires.
A spreadsheet with a currency function and a scheduled script can email you a rate every day. It's a fun afternoon if you like that sort of thing, and a chore if you don't.
Bank alerts exist for some pairs in some countries, buried in settings, and rarely let you say 'below 0.90' in plain words.
The one-sentence way
With MailMeWhen you write the pair and the rule as you'd say it: 'email me every morning with the dollar-to-euro rate and how it moved', or 'tell me the day a dollar buys less than 0.90 euros'. We watch it and write to you — every day, or only when your line is crossed.
The first 7 days are free with no payment details; after that it's $5/month for that one thing, and it stops by itself if you don't subscribe. One reply stops it any time.
Good to know
Name the direction and the number: 'when the pound falls below 1.25 dollars' is unambiguous; 'when the rate is good' isn't.
Published rates are the mid-market rate; what your bank or app charges sits a little off it. Set your line with that margin in mind.
Try it — hand us this sentence:
Email me every morning with the USD to EUR exchange rate and how much it changed since yesterday. Also tell me right away if a dollar buys less than 0.90 euros.
