A misplaced Ecostart survey code blocks access to the questionnaire and prevents any validation of the process. This issue is common, especially when the code has been sent via email several weeks before the response deadline. Here, we detail concrete methods to retrieve it without waiting for a postal resend.
Spam filters and Ecostart codes: the primary cause of real loss
The code is not lost; it is intercepted. The majority of cases we observe are due to filtering on the email side, not user forgetfulness.

Filtering solutions like MailInBlack or Altospam regularly block emails containing confirmation codes. The message ends up in a quarantine folder or disappears before even reaching the inbox. On a professional account, the user often has no visibility on these blocks.
Before taking any other steps, we recommend this systematic check:

- Open the spam or junk folder of the email used during registration, then search for the keyword “ecostart” or “survey code” in the last few weeks.
- If a corporate filter is in place, ask the system administrator to whitelist the Ecostart sending address to unblock future messages and check the quarantine.
- Check the automatic tabs (Promotions, Notifications, Updates) on Gmail and Outlook, which frequently classify transactional emails outside the main inbox.
This step resolves a significant proportion of requests. If the code remains unfound after this sorting, proceed to the methods described below.
We have found that it is possible to retrieve a survey code on Ecostart by combining filter checks with the online recovery options offered by the platform.

Self-service recovery on the Ecostart login page
Recent survey portals have standardized a “Get a new code” button directly on the login page. Ecostart follows this logic: recovery does not require paper mail in most cases.
Locate the resend form
On the access page for the survey, a recovery link is displayed below the input fields. It asks for the information used during the initial registration (email address or identifier associated with the household or establishment).
Enter exactly the email address originally declared. If you have changed your email in the meantime, the self-service procedure will not work, and you will need to go through human assistance.
Time to receive the new code
The automatic resend is almost instantaneous. If nothing arrives within five minutes, the issue returns to the filtering described above. Apply the same spam check before resubmitting a request.
A technical point to remember: each resend request generates a new code that invalidates the previous one. Do not multiply attempts in a burst, at the risk of entering an old code that has become inactive.
Human assistance: when self-service is not enough
Two situations render self-service inoperative: a change of email address not updated in the system, or an account linked to outdated contact information (moving, closing a professional mailbox).
Contact Ecostart support via email or phone
The dual recovery pathway (online and human assistance) is now standard on survey platforms. Ecostart offers a contact form and, depending on the periods, a dedicated phone line.
To expedite processing, prepare these elements before contacting support:
- The email address initially used for registration, even if it is no longer active.
- The first and last name declared, spelled exactly as when the account was created.
- Any additional identifier received by postal mail (file number, survey reference) that allows support to locate the account unambiguously.
We observe that requests accompanied by these three pieces of information are processed significantly faster than those that limit themselves to “I lost my code.”
Changing contact information during the survey
If your email address has changed, support will perform a manual update after identity verification. The new code will be sent to the new address once the change is validated. This process may take a few business days depending on the service load.

Preventing the loss of the Ecostart code during future surveys
Archiving the code as soon as it is received remains the most reliable measure. A password manager (Bitwarden, KeePass, or the integrated browser keychain) accepts secure notes, not just login credentials.
Creating a dedicated email filter is equally effective. On Gmail, a rule like “From: [Ecostart sender address] → Never send to spam + Apply the label Surveys” ensures that the message remains visible. On Outlook, the equivalent is done through inbox rules with the action “Always move to Inbox.”
A code archived in a secure manager does not get lost, even if the original email is deleted months later. This habit prevents reliance on automatic resends or support.
The loss of an Ecostart survey code is almost always resolved without human intervention, provided that spam filters are checked first. When the problem arises from a change of contact information, support remains the only option, but a well-prepared file minimizes the response time to its minimum.
