I am looking for two custom addons for Interspire Email Marketer. Addon1: Multiple MTA for usage of multiple SMTP/MTA Account in each email Campaign Neccessary Features: - Create groups of SMTP accounts. - Send Email Campaigns with more than 1 SMTP account. - Rotate the SMTP Account into GROUP of SMTP. - Select more than 1 SMTP from different groups to send email campaigns. - Use custom Mail-FROM, custom Mail-REPLY-TO and custom Mail-BOUNCE-TO in each SMTP Account. Addon 2: Spining (Content Rotation) "mail from", "reply-to", "bounce-to", Mail Subject, Mail Body and Mail URLs should be spinnable. For spining the mail body I would like to use normal spintax. Payment should be made after completion and everything is working as expected.
