Customers unsubscribe
from important e-mail

Unlike marketing tools, Mail Klerk allows you to hide the unsubscribe button in the footer, preventing customers from accidentally unsubscribing from order-related e-mails.

    Mail Klerk is an e-mail tool designed for convenient and easy bulk mailing. The main advantages of our service are its low cost, simple operation and an administrative environment in English or Czech.

    Learn more

    Bulk e-mails are, as the name suggests, sent out all at once. Notification (status) e-mails are most commonly used for sending invoices, order confirmations, or to access passwords and similar messages.

    Learn more

    The test mode is primarily intended for testing the functions. These are the same as in active mode, but:

    • The test mode sends e-mails through a limited range of IP addresses to protect against spammers.
    • It is also limited by the current queue of all other users in test mode.
    • Therefore, the sending speed does not correspond to the speed available in active mode.

    Learn more

    Yes, to end the test mode, please message us at info@webglobe.com.
