Problem with record summary send mail inline

Problem with record summary send mail inline

Hi guys,

I'm having an issue with multiple elements of a record summary not showing up when sending as email inline. 

[
from :zoho.adminuserid
to : SUrec.Email
subject :"We value your feedback"
message :""
Attachments :template:Send_feedback_email as Inline
]

I have, let's say, 5 elements on the record summary: image, text, spacers etc. 

If someone receives this directly to their email provider (e.g. sent to xx@gmail.com and accesses through gmail) everything is fine.

If someone  receives this using an email client (e.g. sent to xx@gmail.com and accesses through iPhone Mail or Outloook) many of these elements don't show up. Usually just the first one or two elements are visible. 

Can anyone help with what's going on / help me find a solution? 

Thanks!
