MAIL FOR EVERY PROJECT
A home for
every project.
Email for all the domains you own. Give your studio, side project, and next business their own inboxes, and keep them together in Mason.
A few thoughts on the new collection
Hi Alex,
The new shapes look great. I’ve put a few notes together for our call on Thursday.
Looking forward to seeing it all come together.

Their own identities.
An inbox should feel like the project it belongs to.
Change the name, mark, color and signature. Switch without signing out.
The work you’re known for.
Put your studio’s name on the inbox. Use the right sender name, a signature with your logo, and contacts that belong to this project.

Add a domain when you’re ready. Set up its DNS, choose a mailbox, and give it a place beside the rest of your projects.

BEFORE YOU SETTLE IN
Your domains.
A few useful answers.
What is multi-domain email hosting?
It lets you send and receive email using several domains you own. Mason keeps those project inboxes in one workspace, so you can switch between them without signing out.
Do I need to pay for each domain or team member?
No. Mason Pro is $5 USD per month for up to five domains, with five private mailboxes on each. Team members are included. You purchase and renew your domain names separately with your registrar.
Can I use domains I already own?
Yes. Add your domain, verify ownership, and follow the DNS steps to connect its email. Keep your existing website. Namecheap domains can also use the optional DNS connection.
Can each project have its own name and signature?
Yes. Give each project an inbox name, logo or monogram, and accent color. Each sending address can have its own sender name and signature, including images, links, and fonts.
Can my agent use my email?
Yes, when you connect it and approve its permissions. Choose the inboxes and actions it can access, including drafting, sending, organizing mail, and designing signatures. You can revoke access in account settings. Your agent service is separate from your Mason subscription.
What happens if I cancel?
Cancel through Account settings → Billing. Your paid access continues until the end of the current billing period. After that, sending and new setup require an active subscription; your existing mail remains readable.
