The following is a list of frequently asked questions about the MailUp API

Do you charge for use of the MailUp API?

All integrations are available free of charge.

Can I use MailUp to send messages from an external application, without logging into the MailUp admin console?

Yes, see the section on sending messages through MailUp from another system (e.g. a Web site or other SaaS application).

I need to integrate my CRM with MailUp. How should I do?

We have developed two types of integrations, applicable to many systems such as SugarCRM, Salesforce, VTiger and others, which allow to update bidirectionally the user status (subscribed/unsubscribed) inside the CRM. Both types of integration require on your side some work for the development and integration with the CRM. The two ways to integrate are:

Batch FTPFTP-based integration

SOAP or Get/Post APIsHTTP API Examples

My system requires a type of integration not included in this document. Can it be developed anyway?

Our technicians can analyze and evaluate any custom integration between MailUp and other external systems. We may be able to work with you to add features to MailUp that allow an integration with another system. If the requested development can be used by other customers, you may be eligible for a discount on the cost of such development.

Can I install MailUp in my server farm and personalize it?

Unfortunately this is not possible. Here are the two main reasons:

  1. MailUp's architecture consists of several frontend, backend, sql and sending servers, with redundant connections, to ensure the highest level of performance and reliability.
  2. The sending infrastructure is configured so that the sendings are distributed across several IPs, according to constantly changing rules and to the agreements with ISPs, that often also provide guidelines to be followed. We have also signed agreements with many important ISPs, so to allow whitelisting and to prevent messages from being blocked by antispam filters, even with high volumes of emails being sent. MailUp has also agreements in place with ISPs to handle feedback loops. This infrastructure, also connected to domain and DNS management (e.g. DKIM signatures) is hardly replicable externally, both because of its complexity and because it has to be constantly monitored and updated.

How do I create a subscription form that allows subscription to more than one list at the same time?

You can use our HTTP Get/Post API. See Subscribe.aspx.

XMLSubscribe.aspx can be also used, but in this case a confirmation email will be sent for each selected list. As an alternative, it is possible not to send the email, though we would not suggest this practice.

Is there a way to unsubscribe a user from all lists when he unsubscribes from one of them?

You need to activate a post-operation: after the unsubscription, MailUp can perform predefined actions, such as calling external procedures to update a record in a CRM or CMS system, or unsubscribe that user from other lists. The setup of post-operations is available free of charge.
