When you use Gmail as your SMTP service provider in 1and1Mail Account Manager, the account testing may fail. It is usually caused by 2 reasons:

  1. Gmail imposes high security standards. Google may block sign in attempts from some desktop email clients or mobile apps.

    To use Gmail in 1and1Mail, please log in your Gmail via your web browser and go to "Less secure apps" page to turn on "Access for less secure apps".

  2. If your Gmail account has 2-Step Verification enabled, you have to create an application-specific password for 1and1Mail.

Sometimes, you will encounter a pop-up message “Provider cannot be found. It may not be properly installed” when you import .xlsx file (Excel 2007, or Excel 2010) into 1and1Mail Address Book or Multi Account Manager.

Provider cannot be found. It may not be properly installed

 

Cause:

Your OS does not have the library to decode .xslx file.

Solution:

1. Install the new Microsoft library (Data Connectivity Components) from http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=23734

2. Save your .xlsx file as .xls file (Excel 97 – 2003 format) and then import the .xls file.

3. Save your .xlsx file as .csv file, and then import the .csv file.

1and1Mail 3.26 has fixed another 2 bugs:

  • Create table error in non-English OS
  • List index out of bounds error

The complete 1and1Mail changelog can be viewed here.

When you start a mass mailing task in 1and1Mail, sometimes you will encounter a pop-up message: "List index out of bounds (8)".

List index out of bounds

It is usually caused by your modification (import, add or delete) of emails in the address books that are being used by the ongoing task.

To resolve the issue, please restart 1and1Mail and start a new sending task. Make sure there is no change on the address book when the task is ongoing.

When you are sending mass emails with 1and1Mail, sometimes you will see a pop-up message saying "You have reached the daily sending limit. The limit may be imposed by your email service provider or your setting in 1and1Mail." This is usually caused by the following:

1. You have reached the maximum sending amount you have set in 1and1Mail. To increase the sending amount, go to Account Manager, double click the email account you are using, and adjust the number under Sending Policy tab of that account. (1and1Mail suggests you not send more than 100 emails per account in 24 hours.)

2. You have reached the daily sending limit imposed by your email service provider (Gmail, Hotmail, Yahoo! Mail, AOL Mail, GoDaddy, etc.). At this moment, your email accounts or IP addresses may be suspended and it will not be recovered until 24-48 hours later. You can verify this by viewing the Reports. If the last few emails cannot be sent successfully, it is most likely your email accounts are temporarily suspended.

To prevent this from happening in future, there are several things you can do:

  • Send emails to double opt-in contacts only, which means, you should always obtain your recipients' permission before sending mass emails. Unsolicited emails will get you a lot of spam complaints within a short period of time. If that happens, no matter what email clients or email accounts you use, they would be suspended very soon.
     
  • Mimic manual sending by generating random time lag and content spin. The main reason that your email service provider blocks you is because they think you are using a automatic mass mailer spamming thousands of people. With 1and1Mail, you can generate random time lag between sending each email, and also spin different sets of contents in the email subject, body and attachments. This way, you are like a real person manually sending each individual email that looks different to everyone, not a robot trying to spam the world.
     
  • Always remove bounced and unsubscribed from your contact list. Keeping sending to bounced and unsubscribed emails would lead to high bounce rate and spam complaints of your email campaign. Such behavior is harming the email ecosystem, thus, it will seriously lower your Sender Score. Therefore, constantly removing bounced and unsubscribed emails from your contact list is very important to your email deliverability and future revenue stream.
     
  • Use advanced SMTP servers (e.g. turboSMTP) with 1and1Mail. Advanced SMTP servers provide a guarantee on the number of emails you can send out per day or per month through their SMTP connections and high email deliverability.
     
  • Use proxy servers to manage multiple email accounts. Most email service providers set a daily limit on how many emails one can send per hour or per day (Regarding the daily sending limit and send rate of commonly used email accounts, please refer to here). If you want to go over the limit, you can use multiple email accounts with proxy servers in 1and1Mail.
