Recently I submitted a reddit post that became relatively popular within the /r/Stocks subreddit (see the post here).
For a mini experiment I decided to prompt the download with an e-mail request that I would not verify ahead of time.
Here are some stats from the post, along with some of my favorite fake e-mail submissions:
Fake Submissions:
- no@no.no
- whats@this.for
- bob@bob.com
- john@appleseed.com
- lolwtf@aol.com
- senor.poopybutthole@uhhhhh.com
- joanie@loveschachie.com
- agirl@hasnoemail.com
- netflixnchill@myplace.com
- TheTongueTornado@gmail.com
- thepenismightier@snl.com
Some absolute gems there. Let's move on:
| table | Total # | Total % |
|---|---|---|
| Deliverable | 24 | 4% |
| Risky* | 450 | 78% |
| Undeliverable | 104 | 18% |
| Total Collected | 578 | 100% |
From the hunter.io website: When an email address is tagged "risky", it means the server check seems to work, but we have reason to believe the email may not be read by anyone.
This can happen in several cases, for example:
The email seems to be received, but the servers also seem to accept every email address. The email seems to be received, but it looks like gibberish (for example "e9v3mc3@company.com").
| TRUE | FALSE | |
|---|---|---|
| regexp | 578 | 0 |
| gibberish | 99 | 479 |
| disposable | 99 | 479 |
| webmail | 13 | 565 |
| mx_records | 489 | 89 |
| smtp_server | 560 | 18 |
| smtp_check | 555 | 23 |
| accept_all | 506 | 72 |
Average Score: 49
This is the list of verifications:
- Regexp: Verify the format of the email address is correct and looks something like "email@provider.com".
- Gibberish: Check to ensure the address doesn't look like a random email address. For example, 1e49cs1pb6@company.com doesn't pass the test.
- Disposable Email Address: Check if the email address has a domain name used for temporary email addresses.
- Webmail Email Addresses: Verify if the email address uses a webmail like Gmail or Yahoo.
- Presence of MX Records: Check if there are MX records on the domain. If there aren't, the email address can't receive emails.
- Presence of SMTP Server: Check is successful if we are able to connect to the SMTP server (indicated in MX records).
- SMTP Check: Test the email address and see if it bounces or not.
- Accept-all Domain: Check if the server has a catch-all policy which accepts all the email addresses.
Does this mean anything, or teach us anything new?
No. Just thought it would be fun to share.
