What does Rettach do?

Rettach automatically copies the attachments (files) from your email to your cloud storage. It put these files into folders (according to rules), allowing for automatic organization.

What are the supported EMAIL services?

Rettach supports most email services:

  • Office365 (Outlook)
  • Microsoft Exchange
  • Gmail & Google Apps for Business (Gsuite)
  • Almost any other email system that supports standard IMAP4 (Yahoo mail, Hotmail, ZOHO, etc.)

How long does it take between when I receive an email and when it is in my storage?

This varies depending on the type of email and storage systems you have. We try to get new emails and synchronize new attachments as quickly as possible. This may only take a few seconds, or up to five minutes.

Will Rettach sync all of my old attachments?

Yes, Rettach goes through all of your old email and synchronizes all of your attachments

How does Rettach work?

Rettach automatically connects to your email accounts just like an email app on your smartphone, tablet or desktop does. When Rettach detects that you have new emails with attachments, it copies those attachments to your storage accounts (so you don't have to do it manually). The destination folders for these copied files are determined by the rules you choose in Rettach. We highly recommend the pre-built templates, as we have found them to be effective, and they only require a single click! Of course if you'd like to configure or customize your own rules, you can do that too. This is very similar to "email rules", where you setup your email app to organize your emails into folders based on any criteria that you want.

How does Rettach protect my data?

Rettach protects your files by maintaining strong encryption while files are copied. Because we don't actually save your files on our servers, there is no risk to your files being compromised within Rettach. We just copy the files, that's it.

Rettach protects your account data by storing as little information as possible. For almost all public cloud services, we only store the temporary authentication tokens (Oauth2) needed to connect to your service. For services that do not support Oauth2 (such as legacy on-premises Microsoft Exchange, IMAP, or POP accounts), we store your credentials in a separate, private, highly secured, and encrypted database (by comparison, these methods are far more secure that how your credentials are stored in email apps on your phone).

How do Rettach smart rules work?

When Rettach automatically copies attachments to your storage accounts, the destination folders for these copied files are determined by the rules you choose in Rettach. Both templates and custom rules are built from the same basic rules. Here is an example:

Is Rettach for business or personal use?

We designed Rettach for both! As busy professionals, we found email attachments to be a big hassle. We were constantly digging through emails for important presentations, financial documents, contracts, reports, etc. We were wasting valuable time. Sure, we would manually save attachments from our regular computers (when we remembered to), but that took more time, and wasn't effective when we were mobile. We needed our important files at our fingertips when and where we needed them! Personally we also found managing attachments to be a hassle, as family and friends were always sending pictures, videos, and other treasured memories via email. When we were out with friends and wanted to share these memories, we found the hassle of digging up the files to be frustrating, often giving up before even finding the file!

How do I add services to my account?

1 - log into Rettach (this should automatically take you to your dashboard (https://www.rettach.com/user/dashboard/)
2 - go to the 'manage' tab in your dashboard (https://www.rettach.com/user/dashboard/#manage)
3 - Click the big green button at the top labelled "Add another Email or Storage Account"
Note: This is also the process to fix an account that is not working for any reason, simply re-add the same account and it will replace the existing account with the new one.

How do I re-sync one of my accounts?

If for whatever reason, you want to force a re-sync for one of your accounts, the solution is simple, just re-add that account. You can do this easily on your dashboard page:

  1. Go to the manage tab on your dashboard (https://www.rettach.com/user/dashboard/#manage)
  2. Click the button at the top that says "Add another Email or Storage Account"
  3. Authorize Rettach to access your app (same process as when you sign up or add a service)
  4. Now your service should automatically begin a re-sync, which will re-copy all of the attachments, from all of your emails, and save them to your storage account(s)

If you have more than one email account, or more than one storage account, please note that the results will be slightly different depending on what type of account you re-add:

  • STORAGE: If you re-add a storage account, the re-sync will pull email from all of your email services and save those attachments only to this storage account. If you have other storage accounts, and you also want to re-sync those accounts, then you need to re-add those following the same process above.
  • EMAIL: If you re-add an email account, the re-sync will pull email only from this email account and save those attachments to all of your storage accounts. If you have other email accounts, and you also want to re-sync those accounts, then you need to re-add those following the same process above.

What if an account is not syncing?

Just re-add the account to see if that helps. If you are still having an issue, please submit a support request via the link on your dashboard

Do I have to do anything after Rettach is setup?

No, and that is the point! After you add your email and storage accounts to Rettach, everything else happens automatically. The only time you would have to log into Rettach is to add or remove accounts, or to change your rules.

What are the supported STORAGE services?

Rettach supports many popular storage services:

  • OneDrive
  • Dropbox
  • Box
  • Google Drive
  • SharePoint (coming soon)
  • Other services: we're working on adding more services every day, please contact us to recommend a service you would like added!

How do Rettach Security Controls Work?

To prevent “shadow IT”, and to ensure companies have control over where data is stored, Rettach provides strong security controls. Rettach only allows a user to add a service to their account (or setup a new account), if these specific security checks pass:

  1. The company the user belongs to approves the new/additional service
  2. The company owning the email domain of the new/additional service approves the additional service
  3. The company owning the email domain of the new/additional service approves all of the user’s current services

Here is how Rettach handles some common security scenarios:

For the first user in a company:

When the first user at a company signs up for Rettach, a Company account is automatically created, but doesn’t have security controls setup by default. To administer that company account and security controls, the new user must email us at support@rettach.com.

Company Security Setup:

Via Rettach’s security features, ACME company is setup to:

  • only allow Office365 Email (Outlook) and Storage (OneDrive)
  • only allow services signed up with their email domain (@acme.com).

Here is how we protect ACME…

For ACME's users:

This applies to accounts setup with ACME-approved services

John is logged into Rettach with his company Office365 account (john@acme.com), so he is automatically associated with the ACME company (because he signed up with an email address in the @acme.com domain).

  1. John tries to add his personal Dropbox account (john@gmail.com), but Rettach prevents this, because:
    1. ACME does not allow Dropbox
    2. ACME does not allow accounts in the @gmail.com domain
  2. John tries to add his business Dropbox account (john@acme.com), but Rettach prevents this, because:
    1. ACME does not allow Dropbox
  3. John tries to add his business Office365 account (john@OTHERCOMPANY.com), but Rettach prevents this, because:
    1. ACME does not allow accounts in the @OTHERCOMPANY.com domain

For personal accounts:

This applies to personal accounts, or accounts associated with a different company

John is logged into Rettach with his personal Google account (john@gmail.com).

  1. John tries to add his personal Dropbox account (john@gmail.com), but Rettach prevents this, because:
    1. John tries to add his business Office365 account (john@acme.com), but Rettach prevents this, because:
      1. ACME does not allow his existing Google accounts
      2. ACME does not allow his existing accounts in the @gmail.com domain
    2. John tries to add his business Dropbox account (john@acme.com), but Rettach prevents this, because:
      1. ACME does not allow Dropbox

Why did you create Rettach and how does it "free my files"?

Maybe we're just enthusiastic, but we are busy people just like you are, and we wanted to make our lives a little bit easier. We found it to be a hassle to manage all of the files that we get in email, especially when it comes time to find them and use them, or forward them to someone else. We thought that there must be a better way... Wouldn't it be nice if the files that people emailed to us were just there in our storage, when and where we needed them? And of course they would also have to be organized in a logical way. We looked for an existing solution, but couldn't find anything even close, so we built Rettach!

What are the supported file types?

As of today, Rettach does not support attached ".msg" files, otherwise we support all other major file types.

Does Rettach store my files?

No, Rettach never stores your attachments or files on our servers. We just copy the files from your email to your storage, that's it.

What does Rettach provide for companies in terms of value and security?

  • Productivity – When users save time, the company has more efficient users, it’s a win-win!
  • Collaboration – If users are synced to “shared” storage, then Rettach is effectively a DMS (Document Management System), automatically saving and sharing files for groups
  • Security – Rettach provides Enterprise-grade security features
    • Control – Companies (or 3rd party administrators) have granular security controls to allow specific users or groups to access certain services. The most common use case is that a company can “lock down” their users so that they can only add company-approved email and storage services.
    • Administration and visibility – Companies have full administrative visibility into all of their users, accounts and related activity.
    • Secure Data at rest – Rettach doesn’t store any customer emails or files, so the only place the customer’s emails and files are located are in the same services they already use (no additional exposure of data at rest)
    • Secure Data in transit – Rettach encrypts all customer data end-to-end, using the same security protocols are the email and storage services themselves (just like an email or storage client app)
  • Support - 24 x 7 x 365 tools – your users always have access to support

How do I sync my emails?

To enable sync for emails, a user can do one of two things:

1 - New accounts - It will not start saving emails until you have checked that box. So if you’re setting up a new account, customize the rules during account creation (hit “I want to customize my rules”), and click a button at the bottom called “also save all my emails”, then select yes, and then complete the signup process.

2 - Existing accounts - First go to your settings page, and check the box that says “Save my emails”, then hit save. Then go to your rules and hit “reset rules to default”. (To sync old emails, you need to resync your email accounts) Then, to resync, click on the "resync one of your accounts" button and follow the instructions.

Should I save my emails as PDF or EML files?

We generally recommend PDF, but it depends on how you want to use the files.

PDFs are great when you want an archival copy of your email to refer to. It is readable on any device, and can be searched for content easily. However, you cannot open the PDF as an email and simply reply-to or forward it. You would have to attached the PDF to a new email to send it.

EML files are good if you only want to use them for backup, and/or only want to use them with a desktop email app that supports .eml files, like Outlook. You can open these files on the desktop, and then reply-to or forward to them (they ARE emails). However, you cannot use or view .eml files on most mobile devices, and you cannot open/preview them in the web-based tools for your storage (you must download the file). Also, .eml files are not searchable by your desktop or online storage services (because the content is MIME encoded).

I have an Outlook.com address, which type fo service should I pick?

Outlook.com addresses (formerly Hotmail) can be added via either Exchange, or IMAP.
