Add the ability to initiate email messages and add/remove contacts from lists based on subscriber actions.
Better segmentation options
Segmentation options are rather limited right now. Even a simple set of "I'm interested in" options for subscribers isn't possible. This could be significantly improved in two ways: 1. add the option to segment based on wp_usermeta fields. This would allow me to gather subscriber information by many other methods (Gravity Forms, Buddy Press, etc), and then create email segments based on that. 2. add a PHP API which would allow me to define my own segments by any criteria I want. While this would require a developer to take advantage of, it might make it easier for creating new segmentation options in MailPoet itself, so possibly worthwhile for both third party and your own developers :-)
Statistics per subscriber
We want to add detailed statistics per subscriber. You will be able to see for each subscriber, which email they opened and which links they clicked!
Option to send confirmation e-mail for imported list and auto-triggering welcome emails for imported list
Option to send a confirmation e-mail automatically (or trigger welcome emails already set up) when new e-mails are imported or manually added to a list. Having to ask them to resubscribe from scratch almost immediately after they already opted in (or potentially double opted-in) from a program MailPoet isn't integrated with just because we can't send a confirmation email is very much not ideal. Having to use the current workaround (import them into a list and send a newsletter manually before then manually moving them to the original list we want them on) is an incredibly time-consuming task that has to be repeated constantly as new subscribers sign up for the list with whatever program you're using that MailPoet doesn't integrate with (e.g. kingsumo, bookfunnel).
Multiple Confirmation Email For Each List Type
When managing different lists, it is difficult to create just one confirmation email for all lists. We have an 'enquiry' list, which will only get a max of 3 automations, to do with their enquiry, so the using a generic confirmation email is very confusing to the customer.
Whitelabel for Agencies (won't do!)
Ability for agencies to rename the MailPoet WP menu item and any other brand mentions
Change Spammy Rules
This is a fairly decent plugin, especially for agencies. But, the threat of the MP team blocking my entire account because of client "17" doing some spammy crap is a HUGE deterrent. Why use this plugin if you've got the option to close my entire account? I wouldn't. If you would, please change this to be per website and not for the whole account. At least that would be something that we can deal with. Especially from an agency perspective.
Mail Sending Service on a Per List Basis
It would be great to have the option to select the mail sending service on a per list basis. This way if someone came into a cart abandonment list, you could follow up with them through another sending service like SendGrid or Amazon SES that doesn't require a double opt-in. Once a purchase takes place, then they could be put on the list that runs through the MailPoet service and requires a double opt-in.
Simple CRM with email send/open history & contact properties
This feature will be powerful where we can collect custom information through MailPoet forms & save it as custom contact properties. Simple segmentations can be created through this (as opposed to tag-based autoresponders). Besides this being able to view email sends/opens history for the contact will be very useful as well.
