We generally operate a 50MB limit for email message size. Many ISPs block messages that are larger than 20MB, so a 50MB limit is quite substantial. Please note that this 50MB limit is for the complete email message, including attachments. If you wish to send and receive very large files then you should consider using a service like [https://wetransfer.com/](https://wetransfer.com/) or a cloud-based filing sharing service like DropBox or OneDrive. Email was never intended or designed to be a large file transfer protocol. - [Getting Started](https://help.blakemarkdigital.co.uk/getting-started) - [Web Hosting](https://help.blakemarkdigital.co.uk/web-hosting#main-content) - [Elementor](https://help.blakemarkdigital.co.uk/web-hosting#elementor) - [WordPress](https://help.blakemarkdigital.co.uk/web-hosting#wordpress) - [Security](https://help.blakemarkdigital.co.uk/web-hosting#security) - [Email](https://help.blakemarkdigital.co.uk/email#main-content) - [Mail Clients](https://help.blakemarkdigital.co.uk/email#mail-clients) - [SpamExperts](https://help.blakemarkdigital.co.uk/email#spamexperts) - [MailChannels](https://help.blakemarkdigital.co.uk/email#mailchannels) - [Domains](https://help.blakemarkdigital.co.uk/domains#main-content) - [Domain Privacy](https://help.blakemarkdigital.co.uk/domains#domain-privacy) - [Billing](https://help.blakemarkdigital.co.uk/billing) - [cPanel](https://help.blakemarkdigital.co.uk/cpanel#main-content) - [JetBackup](https://help.blakemarkdigital.co.uk/cpanel#jetbackup) - [Softaculous](https://help.blakemarkdigital.co.uk/cpanel#softaculous) - [WordPress Glossary Terms](https://help.blakemarkdigital.co.uk/wordpress-glossary-terms#main-content) - [H](https://help.blakemarkdigital.co.uk/wordpress-glossary-terms#h) [![Blake Mark Digital Logo](https://help.blakemarkdigital.co.uk/hs-fs/hubfs/Asset%205.png?width=250&height=71&name=Asset%205.png "Blake Mark Digital Logo")](https://blakemarkdigital.co.uk/) Blake Mark Digital is a digital marketing agency supporting SMEs and non-profits with strategic branding, content, and campaigns that drive real results 124-128 City Road, London, EC1V 2NX [support@blakemarkdigital.co.uk](mailto:support@blakemarkdigital.co.uk) +44 20 4578 9582 [mailto:support@blakemarkproductions.com](mailto:support@blakemarkproductions.com) Copyright © Blake Mark Productions Ltd
