Bring your custom-domain mailbox
Connect a provider that supports secure IMAP and SMTP. SyncMail does not force your business mail into a new hosted service.
CUSTOM IMAP · WINDOWS + ANDROID
Everyday email without another monthly app subscription.
Bring the secure IMAP and SMTP mailbox you already use—including custom-domain business email—to Android and Windows. Keep mail with your provider while drafts, signatures, and sender details follow you between devices. Google and Yahoo accounts are supported, too.
Use the mailbox you already own
SyncMail gives standard IMAP users a polished Android and Windows experience without forcing mail into a new hosted service. You do not need Microsoft 365 just to use a compatible custom-domain mailbox in SyncMail. Google and Yahoo remain familiar account choices.
BUILT FOR INDEPENDENT EMAIL
Your domain. Your provider. Your workflow.
A consistent Android and Windows experience, with your signature and sender details available on both.
Write your signature once
Your signature and sender name are encrypted before SyncMail stores them in your own mailbox, then recovered on your other SyncMail device.
Continue between phone and PC
Mail, folders, read status, stars, and drafts synchronize through your email provider. Start on Android and continue on Windows.
Try your real accounts first
Trial-enabled releases offer 14 days free on supported Windows and Android devices. No payment is needed to start and there is no automatic charge. Continue with one $5.99 purchase.
What you still need: an existing email mailbox from a provider that supports SyncMail’s secure connection methods. Email hosting charges, domain registration, and provider policies remain separate.
POPULAR PROVIDERS, TOO

Yahoo
Yahoo works with its secure provider-issued app password and built-in mail-server settings.
Other secure IMAP
Connect business and personal providers that publish or supply secure standard IMAP and SMTP settings.
Microsoft
Microsoft browser sign-in is prepared and will be offered after Microsoft completes its provider approval.

POPULAR ANSWERS
The usual fixes
Sign in securely
Use the full email address and the secure IMAP and SMTP settings supplied by your email provider. SyncMail does not allow unencrypted mail connections.
Refresh your mailbox
Mail checks automatically while SyncMail is open. On Android, pull down on the message list when you want an immediate check.
Continue a draft
Sign into the same mailbox on both devices. Provider draft synchronization uses that account’s Drafts folder.
Carry your signature with you
SyncMail encrypts your signature and sender name before saving the synchronization record in your own mailbox.
Protect your password
Never send a password, recovery key, private email, or attachment to Support. We can troubleshoot without them.
14-DAY TRIAL · ONE PURCHASE
Windows and Android together
In a trial-enabled release, choose Start or resume free trial and verify your email to use your real accounts for 14 days. The same trial end date applies on both platforms. No card is needed and nothing is charged automatically. After the trial, choose whether to buy SyncMail for $5.99 one time through Google Play; the purchase covers up to 20 active supported Android and Windows installations.
The 14-day trial is available in the Windows 0.76.116 download. The Android trial update is awaiting Google Play approval. Older builds without the trial option still require purchase activation. Existing purchases remain valid. There is no recurring subscription.

Paid-app support aims to respond within three business days.
