One of the most used features of MoreApp is sending an email with a PDF attachment after a form is filled in. Learn how we send those emails and what to do if you don’t seem to receive them.

Chances are that you’ve heard of the company MailChimp. They provide a service that allows their users to design and send email campaigns. Their product is so successful that they decided to create a service out of their email servers, this is called: Mandrill and through this service, they literally send billions of emails each month and is trusted by more than 500,000 customers worldwide.

Sending emails might sound simple, but in reality there are a lot of things to take into account. We decided to not reinvent the wheel and entrust MoreApp’s mail sending capability to Mandrill. The result? We send tens of thousands of emails every month with an amazing 99.2% deliverability.

The (less than) 1%

But where do those 0.8 % of emails go? There are a number of possibilities:

1. Check your registration

Go to the Registrations tab in the Platform. Is there a green check mark visible in the Email column? Then you know that everything went well. If you see an orange triangle or red cross, you can click on it to see what went wrong.

If you have configured the mailserver Mandrill yourself (part of branding), you can also check the status of the emails in Mandrill. In Mandrill, go to the Outbound tab. If you search for the email address there, you will see exactly when the emails were sent from Mandrill. Experience shows that it is almost always the receiving mailserver that ensures that emails do not arrive immediately. They may be stuck in an internal queue or spam filter. You can check this with the administrator of your mailserver.

2. Size

Most mail servers won’t allow you to send a mail that’s bigger than 25mb in total. For most mails this is more than enough. But if your form includes a lot of photo’s, Pin-widgets and signatures and you’ve chosen to attach photo’s to the email then you can quickly reach this limit. You can choose not to add the photos as a separate files by unchecking the Attach all images checkbox in the Email tab. You can also check the settings of the Photo-widget. If the mail is still too large, you can ask the administrator of the mail server to raise the limit. 

3. Whitelist

Another option, although definitely not very common at all, is that your mailserver might be actively refusing to receive our mails. The only way to check this is by contacting your mailserver provider to whitelist the MoreApp domain.

Hopefully, this post allows you to resolve any problems you may be having. But as always, you can contact MoreApp support if there are any questions.
