- Are you working tirelessly to increase conversion in email mailings?
- Do you want to decrease bounce rate?
- Do you want to know who owns an email address or phone number so that you can save time and money?
- Do you want to keep your email list clean and only contain real potential customers?
- Do you want access to a working email API?

I answered yes to all the above questions. I'm an online course creator, tutor, and coach. Email marketing is critical to my business.

PROS
---------------
Mailcheck's email API acts as a filter between my website and my existing or potential customers. It screens out bots that could get into my email list and possibly damage my business unless they are captured on time and in real-time.

I bought Mailcheck because it has a built in API integration feature that validates my email database in real-time. People signing up on my website forms using fake emails are instantly banned before they get on to my email list. It's the only way to keep my email list clean.

MailCheck's API documentation is detailed and thorough. With it you can,
- Validate your mailing list in one click
- Get assured your mailing list contains only real emails addresses, get rid of bots and inactive users
- Multiple operations options on emails include:
- Create batch check operations
- Request batch check operation status
- List batch check operations
- Process single emails synchronously
- Detailed model and example code is provided for each operation

- Quick validations are provided for single email checks.
- Detailed example code includes: Curl, Go, Javascript, Python, and PHP

- Verify bulk emails
- Up to a 100,000 emails can be validated at one time using direct upload via CSV, WP plugin, or Mailchimp.

- Use multiple single codes to connect 5 of your sites to multiple Mailcheck email API integrations. What more could you ask for? Perfect!

Also, my company is based in the UK, so it's great that Mailcheck is GDPR Compliant and thus will never share your data.

CONS
---------------
Although, the credits are one-time-use, they never expire.

Overall, Mailcheck is a solid email list validation platform. It's shining light feature is it's email API and the detailed documentation. Highly recommended.
