MySigMail – UI Email Signature Generator

I'd caution others against using the embedded image functionality even if it seems cleaner/more reliable. It bloats out the size of the email you're sending too much. For example I added a 5 KB JPG image, populated all the default fields, and the resulting HTML was 70 KB. This seems to be the result of BASE64's inefficiency.
You could alternatively upload the image to e.g. Amazon's S3 and link to it instead. That way you have completely control, and there's some redundancy there.
According to my back of napkin maths, Amazon's S3 would cost less than 5c/month, assuming millions of requests, and the same 5 KB thumbnail.
I really like this open source project in general. Again, this is in no way a criticism of them, there's no other way I know of to embed an image.
You might need a bigger napkin.
For 1 million requests, S3 will cost you $0.40, excluding storage or other transfer costs. 5 million would be $2.
It's not free, but also '5c/month for millions of requests' is a tad bit off.

This is assuming a 5 KB image, no free tier, US East, S3 Standard, and at least 1m requests (GET/SELECT). I'm including data out and data transfer.
GET, SELECT and all other Requests $0.0004 per 1,000 requests
1000 * 1000 is $0.40 for the requests.
On the calculator link you sent, I put in "1000000" in the GET/SELECT requests, and see "Estimate of your Monthly Bill ($ 0.39)"
* It looks like you're tracking which recipients read your email and when. Spammers do this a lot (or rather they used to) with single-pixel images called "tracking beacons". You send an email to millions of people, give each one a slightly different <img> link, look at the server log to see which images got downloaded, and those are your suckers.
* Because of the previous point, most email clients don't load images from external sources by default. They pop up a little notification bar saying something scary like "Click here to load unsafe images", because "Click here to load external images that might cause spammers to see whether you've looked at the email" is too complex. So your emails all now come with a scary warning, and most people won't see your image anyway.
