Getting started
- The path of a forwarded email Follow one message from the sender's server to your inbox: MX records, spam check, alias match, delivery and the log entry.
- Your forwarded email lives in your own inbox Mailyoto runs no IMAP or POP server. When a mail app asks for an incoming server, enter the settings of the inbox your alias forwards to.
- Add your domain Add your domain to Mailyoto, copy its MX and SPF records into your DNS provider, and verify that forwarding works.
- Navigate DNS tab What each table, column and mark on a domain's DNS tab means, and what the Check DNS button does.
- Domain status What the Forwarding, Sending, Blocked and Frozen pills on a domain mean, what changes them and when Mailyoto checks again.
- Import many domains Add a list of domains at once, read the result for each domain, then add each domain's DNS records.
- Dashboard shortcuts Every keyboard shortcut in the Mailyoto dashboard, the command palette, and how the log search reads what you type.

Aliases and routing
- Aliases and the catch-all Create, edit and delete aliases on your domain, and decide what the catch-all does with every other address.
- Forward an alias to multiple inboxes Give a shared address such as orders@ up to 10 destinations, one for each person who needs its email.
- Pattern aliases With a * in its address, one alias covers a family of addresses and can build each destination from the address.
- Plus-addressing Add a +tag to any alias, such as hello+shop@, without creating anything. Mailyoto forwards the email without the tag.
- Pause an alias Stop an alias from forwarding until you resume it, and choose whether its email returns to the sender, waits, or is discarded.
- Keep only important email Drop newsletters and promotions on an alias you give to shops and services, and still receive receipts, codes and password resets.
- Block a sender from an alias Stop one sender reaching an alias with the Unsubscribe button in your mail app, keep everyone else's email, and undo it later.
- Confirm an alias forwards Send a test email to an alias, find it in Logs, and read what each status means for the email.
- Import aliases from a list Add as many aliases as your plan allows on a domain at once, from a pasted list or a CSV file, and read the result for each line.
- Route email with rules Add rules that Mailyoto applies before a domain's aliases. Each one looks at the sender, the address, the subject or the body, then forwards, drops or rejects the email.
Sending and replies
- Reply from your alias On Pro and Max, press Reply on a forwarded email in any mail app, including a phone app, and your response is sent from your alias.
- Create sending credentials Create the username and password your mail app uses to send through Mailyoto, choose the addresses it sends as and when it expires, and reset or revoke it later.
- Send as your alias from Gmail Add your alias under Send mail as in Gmail's settings with a Mailyoto credential. New email and replies then come from your own domain.
- What keeps working when Gmail ends Send mail as Google is removing Send mail as for addresses it doesn't host. Forwarding and replies from your alias keep working in Gmail, and other mail apps can send as your alias.
- Your alias can show a profile picture in Gmail Create a Google Account for your alias address. People who read your email in Gmail then see your picture next to it.
- Send as your alias from Outlook Which Outlook versions can send as your alias through Mailyoto, how to set up classic Outlook for Windows, and what to use otherwise.

- Send as your alias from Apple Mail on Mac Add your alias to Apple Mail on a Mac so it reads your inbox as before and sends as your alias through Mailyoto.
- Send as your alias from Zoho Mail Add your alias to Zoho Mail as an external From address on Mailyoto's SMTP server, confirm it, and pick it when you write.

Logs and delivery
- Email is not arriving Find out why an email to your alias didn't reach your inbox, and fix the cause in the right place.
- Trace an email in your logs Find any email your domains forwarded or sent, see what happened to it, and read each server's response.
- Resend a failed email Send a permanently failed forwarded email to its destination again, once you have fixed the cause.
- Save an email as an .eml file Get the full copy Mailyoto stored of an email, to open in a mail app or read its source.
- Export or clear your logs Download up to 30 days of a domain's logs as a CSV file, or delete its log history permanently without stopping forwarding.
- Hard and soft bounces What a hard bounce and a soft bounce mean in your logs, how Mailyoto retries, and what to do about each.
- Blocked destinations Why Mailyoto stops forwarding to an address that refuses email, which aliases a block affects, and how to lift it.
- Forwarding limit reached Why senders get a 452 refusal from your domain, what the monthly allowance counts, when it starts again and how to raise it.
- Read message headers Open the full headers of a forwarded email in your mail app, and read the lines that show how it reached you.
- Spam checks Mailyoto scores every incoming message and refuses spam for every alias. You can keep a copy of refused email to download.
- No sender can skip the spam and blocklist checks What makes Mailyoto refuse a sender on every account, and how to ask us to review a refused email.
Fix a problem
- What each mail server response means What each refusal from Mailyoto's mail servers means, quoted exactly, and who needs to act on it.
- Email refused because of a blocklist Why Mailyoto refuses email from servers and domains on public blocklists, and how the sender gets delisted.
- Gmail hides a test you send yourself Use Send test to watch an alias forward to Gmail, which keeps an email you sent yourself out of your inbox.
- Keep forwarded email out of Gmail spam A Gmail filter that keeps every email sent to your alias out of Spam and in your inbox.
- Forwarded email goes to the Spam folder What sends some forwarded email to Spam, and the checks that move it back to your inbox.
- A DNS record still shows a cross Compare each record with the DNS tab, then work through the common causes, from the wrong DNS provider to an old DNSSEC setting.
- Email refused because of DKIM When Mailyoto refuses forwarded email that lacks a valid DKIM signature, when it delivers it from a reply address instead, and what the sender changes to fix it.
- Some forwarded email has no Mailyoto DKIM signature Why only some forwarded messages carry a Mailyoto DKIM signature, what the ARC seal does, and how DMARC is affected.
- Email refused for a line that is too long Why Mailyoto refuses a message with a very long line, and how the sending software fixes it.
- Email refused for being too large The size limit Mailyoto applies to every email, the refusals a sender sees, and how to share large files instead.
- Mailyoto can't send mail for your domain yet The refusal your mail app shows while your domain has no DKIM record, and the records that fix it.
- A checker warns about reverse DNS on our MX servers Servers that deliver to you never check the reverse DNS of mx1 and mx2.mailyoto.com. A checker's warning about it changes nothing for your email.
- Stop forwarded spam Where Report spam on a forwarded email sends the complaint, and the dashboard tools that stop the spam at Mailyoto.
DNS records and mail services
- Set up DKIM Copy the 2 DKIM records from your DNS tab to your DNS provider. Mailyoto then signs the email you send as your domain.
- Set up DMARC Publish a DMARC record for your domain, start with p=none, and tighten it once you know who sends as you.
- Merge SPF records Combine Mailyoto's SPF include with your other email services in one SPF record that Mailyoto can verify.
- Forwarding starts once SPF includes Mailyoto What the spf.mailyoto.com include does for forwarded email, and why the Forwarding pill waits for it.
- One forwarding service per domain What happens to your email when 2 services share your MX records, and the one backup setup Mailyoto accepts.
- Allow backup MX servers Choose whether your domain may keep another mail server's MX records next to Mailyoto's, and what the DNS check accepts either way.
- Share a domain with your mail host Keep inboxes at Google Workspace, Zoho Mail, Microsoft 365 or another mail host for some people, and send every other address on your domain to Mailyoto aliases.
- Use your own domain in DNS records Set a white-label domain so your customers' MX, SPF and DKIM records name your domain instead of Mailyoto.

- Ways to sign in Sign in with a password, an email link, a passkey, or Google or GitHub, and set a password on an account that has none.
- An account email on your domain must forward elsewhere Why an account email on a domain you forward creates a loop, and the setup that keeps your email arriving.
- Turn on two-factor authentication Ask for a 6-digit code from an authenticator app at every sign-in, and keep 10 recovery codes in case you lose your phone.
- Sign in with a passkey Add a passkey so you sign in with your fingerprint, face or device PIN instead of typing a password, name each one, and remove one you no longer use.
- Manage signed-in devices See every browser signed in to your account, with its country and when it was last used, and sign out one device or all but this one.
