1and1Soft receives many email enquiries every day. Even for 1and1Mail Free Edition users, we still try to answer all of their questions and solve their technical problems. However, some emails do not clearly specify the situation they encounter, so there are lots of "Re:s" and "Fw:s" back and forth, causing the delay of the final solution.

Therefore, here we would like to propose a few things that would facilitate the communication:

1. 1and1Mail FAQ page is a good resource to find the quick solution. Customers are very welcome to check the page first.

2. 1and1Mail QuickStart Guide and Video Demo vividly demonstrate the important steps to set up accounts and start the first email campaign step by step. These instructions are very helpful for non-tech people to get started with the software.

3. When there is a need to send an email enquiry, it is highly recommended a screenshot of the situation you encounter can be included in the email. It can help 1and1Soft software team to identify the problem much faster.

4. If possible, also include the screenshot of the "Task Log" (right click the task and choose "Task Log", and capture the "Recipient" tab).

5. Tell us what type of email accounts you are using. Free email accounts (e.g. Gmail, Yahoo Mail, Hotmail, etc.), paid email accounts (e.g. GoDaddy) and company email accounts do vary a lot in the capabilities in sending mass emails.

6. Tell us your settings in 1and1Mail. What is the time lag / time interval? How many emails have you sent out per day?

Following the above instructions can help both of us solve the problem as quickly as possible and make your email marketing more efficient.

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.
