Feature requests

Hello MailPoet Team, I am using MailPoet to send emails via a custom SMTP server ( api.samotpravil.ru ). My SMTP provider requires that I include the header Precedence: transaction in all outgoing emails to disable their local stop-list. I have tried several approaches, but the header either doesn't get added or is overwritten. I need guidance on the correct MailPoet hook to use. Environment details: MailPoet version: last WordPress version: 6.x Sending method: SMTP (configured with host api.samotpravil.ru , port 1126) What I've tried: Using WordPress phpmailer_init hook — this works for regular wp_mail() but doesn't seem to fire for MailPoet's sending process. Using MailPoet's mailpoet_mailer_smtp_options filter — I can see in the debug log that my function is called and I add the header to $options['custom_headers'], but the final email still shows Precedence: bulk. Here's the code I used: php add_filter('mailpoet_mailer_smtp_options', function($options) { $options['custom_headers'] = ['Precedence:transaction']; return $options; }); Using mailpoet_mailer_smtp_transport_agent — this filter is marked as deprecated in your documentation, but I tried it anyway. It either doesn't fire or the header is still overwritten. My questions: What is the correct and currently recommended hook in MailPoet for adding custom SMTP headers (like Precedence) to all outgoing emails? Is there a way to ensure that my custom header overrides any default header that MailPoet might be adding? Could MailPoet be adding a Precedence: bulk header automatically? If so, how can I prevent this or replace it with my own? If mailpoet_mailer_smtp_options is the right filter, why might my header not appear in the final email, even though it's present in the $options array? Debug log entry (showing my filter is called): text [07-Mar-2026 11:51:51 UTC] === Added Precedence exactly as in support example === [07-Mar-2026 11:51:51 UTC] Header: Precedence:transaction But the received email still shows: text Precedence: bulk Any guidance would be greatly appreciated. I'm happy to provide more details or run additional tests if needed. Thank you

If you open the code editor of a text block and type in <ol start="3"> so your list starts at 3, 4, 5, when you click save the attribute is deleted and the list starts at 1, no matter what.

If a newsletter is being created in Google Docs and it contains a bulletted list, when you copy the content into Mailpoet the bullets are rendered in incorrect spots until you unbullet and rebullet the sections.

Because abandoned cart emails are considered "transactional", there's no option for someone to opt-out. Please implement this as it would reduce complaints and allow for a better customer experience.

It would be useful to be able to trigger the popup form by clicking on a button. The popup form would need to allow the designer to specify an anchor name that they can then use to attach to a link or button. The form can then be inserted using the other controls (all pages, all posts, specific pages, specific posts, via shortcode, etc) but the trigger would be limited to the click event.

1) Jetpack Forms play nice with Gutenberg and the Block Editor. They better inherit theme styling and global styles. They use Block Editor Buttons for Submit (instead of HTML input). They just look better in a modern block theme without much fussing. Please make Mailpoet Forms play nicer with the Block Editor in the same way Jetpack Forms does. 2) Please work with Jetpack Forms team on their Integration so the Radio, Checkbox, and Dropdown blocks can map to Mailpoet Lists the way it does in Mailpoet Forms. Both of these fixes would unify the experience between the two products (and I understand now you're sister companies). Thanks!

I use different forms for different audiences on my website (B2B & B2C). I already use E-mail automation (trigger Opt-In) and a special landing page for each form, but I would really appreciate it if I could use different opt-in e-mails for every form/list. Specially for the B2B list that would look more professional.

Title says it all! Would be nice if it could be radio input or checkbox input when users are selecting mailing lists from the custom mailpoet form

You should really optimize how you save the email sending queue in the table _mailpoet_sending_queue. On my websites, for the bigger one, this table is several Go and continues to increase with time... until the server crash. Why are you saving each email in plain HTML in the database? You should save only one version of the global email and then optimize to call this email for each user... not save each email in the table, I have dozen of thousands of the same emails in my table... Really, they're a lot of improvements to be done here! It's ok for small websites but for bigger ones it's not really possible.
