Frequently asked questions and answers about Constant Contact

How can I migrate my existing contact lists to Constant Contact?

Constant Contact does not allow you to import contacts from another email marketing provider. In other words, this means you'll need to build your contact lists from scratch. The best thing you can do is send an invitation email to your current lists, let them know you're switching to Constant Contact, and ask them to subscribe to your lists with the new provider.

How can I use the follow-up autoresponder?

To use the autoresponder function of Constant Contact, first create a list and link it to a subscription form. Next, create an autoresponder and link it to a series of emails. Finally, link the autoresponder to the corresponding contacts list. If someone now subscribes to the list, then they will receive all emails from the autoresponder according to the specified interval.

Can I edit the HTML source text in the email builder?

Yes, this is possible. But please note the restrictions that prevent the use of potentially dangerous HTML code in the email. If you try to include an iframe in the email, for example, this will not work due to potential misuse.

What are basic and advanced statistics?

Basic statistics often refer to the performance of an email, for example the open or click rate, sometimes you can also see the clicked links. Advanced statistics often go much deeper and show more of the user's behavior and often information about their device or even interests can be viewed.

Has Constant Contact implemented IP reputation management?

Our automated systems that monitor each provider's IP history indicate that Constant Contact must have IP reputation management in place to ensure that IPs are as clean as possible to maximize email deliverability.

How does Constant Contact deal with email SPAM?

Constant Contact takes the handling of SPAM and complaints very seriously. They prohibit any SPAM activities to ensure that other customers do not suffer harm from third party negligence, to maximize the deliverability of emails and to protect the reputation of both parties.

Can I implement an external behavior analysis solution?

There is actually an option at Constant Contact to integrate your own analysis solution, for example Matomo.

How to set up custom analytics with Constant Contact?

Open an HTML email or template and change the mode from Visual to Source. Copy and paste the tracking code from your analytics software into the HTML source of the email or template. Save the changes.

Does Constant Contact offer a free plan?

Yes, Constant Contact offers a free plan. You can register a free account and use the basic features for free to start your email marketing without obligation.

Constant Contact does not support email attachments, how can I send files to my recipients?

It is common practice for email marketing providers to prohibit email attachments, as these are often misused to send malicious files to email users. This can even have a negative impact on the deliverability of emails. If you want to send files with your emails, simply upload the file to your website or a file-sharing platform first and include the link in the email body.

Is a payment method required for the free plan?

No, currently the free plan can be used without providing payment information.

What payment options are available?

By default, there is a monthly payment option for the selected tariff. It is also possible to choose the annual payment option. When it comes to payment methods, you can pay via PayPal, credit card, or ask Constant Contact directly whether they can offer an alternative payment method.

Does Constant Contact offer a money-back guarantee?

No, Constant Contact does not offer a money-back guarantee. However, the small tariffs are very inexpensive, so the financial risk is rather low.

What is GDPR compliance?
