email-seems-valid
An offline check to see if an email seems valid.
Contains TS or JS packages for browser or Node.js
```typescript
emailSeemsValid('test@gmail.com'); // true
emailSeemsValid('i̇test@gmail.com'); // false
emailSeemsValid('test@gmail.ocm'); // false
emailSeemsValid('test@protonmail.co'); // false
```
---
## Why is this needed?
Tools like Amazon SES are picky about email addresses. It's very technical, but this library is a good offline validator that an address will work for Amazon SES and all other email senders
## Usage
```typescript
import { emailSeemsValid } from 'email-seems-valid';
// simple valid email addresses
emailSeemsValid('test@gmail.com');
emailSeemsValid('test@protonmail.com');
// all true
// special characters
emailSeemsValid('!test@gmail.com');
emailSeemsValid('!test@gmail.com');
emailSeemsValid('ñtest@gmail.com');
emailSeemsValid('i̇test@gmail.com');
// all false (Amazon SES rejects exclamation points)
// common mis-spellings
emailSeemsValid('test@gmail.ocm');
emailSeemsValid('test@gamail.com');
emailSeemsValid('test@protonmail.co');
// all false
```
This library does not provide accurate true/false all emails, but it works for 99.95%.

## More Details
> Amazon SES does not support the SMTPUTF8 extension, as described in RFC6531. For this reason, the local part of a destination email address (the part of the email address that precedes the @ sign) may only contain 7-bit ASCII characters. If the domain part of an address (the part after the @ sign) contains non-ASCII characters, they must be encoded using Punycode, as described in RFC3492.
