Hi,
I'm an email marketing expert with relevant skills set including HTML expertise, design experience on Photoshop, and an eye for aesthetic and fluid design.
I can extract the 20 odd images from your email template and code the same into a well designed HTML template with inlined CSS. This can then be used on any email marketing software like MailChimp, MailJet, etc.
Looking forward to hearing from you.
Regards,
Swati
