Setting up a newsletter and email marketing after moving to WordPress

The subscriber list you almost left behind

Here is a scenario I have seen more than once: the site migration is celebrated, the AI builder subscription is cancelled, and two weeks later someone asks where the four hundred newsletter subscribers went. Answer: they lived in the builder's built-in email tool, and they are gone with the account. Email lists are one of the most valuable and most forgotten assets in any migration.

So before anything else: export your subscriber list from the old platform while you still can, including the signup dates and consent status. That export is both your business asset and your legal proof that people opted in. Store it somewhere safe before you cancel anything.

Choosing a newsletter platform

WordPress itself can send newsletters through plugins that use your own SMTP, which is fine for a few hundred subscribers and simple announcements. Beyond that, use a dedicated email marketing platform: they handle deliverability, bounces, unsubscribes and legal footers far better than any plugin, and their sender reputation is their core business.

When comparing platforms, look past the free tier price. Check the price at three times your current list size, whether automation (welcome sequences) is included, how good the WordPress integration is, and whether the company and its data processing fit your GDPR obligations. Migrating email platforms later is doable but annoying, so choose for the next three years, not the next three months.

Importing your list without legal or deliverability damage

Two rules when importing. Legal rule: only import subscribers who genuinely consented, and keep the proof. If your old export mixes customers, contacts and real subscribers, split it and import only the real subscribers; padding a list with people who never opted in is both illegal in Europe and bad for delivery. Deliverability rule: clean the list first. Remove hard bounces, obvious role addresses and addresses that have not opened anything in years. Sending to a dirty list in your first week on a new platform destroys your fresh sender reputation immediately.

Send the first campaign to your most engaged segment, people who recently opened or clicked, rather than the whole list at once. A healthy first send teaches the receiving mail providers that your mail is wanted, which benefits every future campaign.

Connecting the signup forms to WordPress

Recreate the signup forms with your platform's official WordPress plugin or embed code, and place them where the old site had them: footer, blog sidebar, after posts. Then check the full flow once with your own address: signup, confirmation email (use double opt-in, it keeps the list clean and proves consent), welcome email, and appearing in the platform's list. Also decide where the 'unsubscribe' and preference links lead, and test them; a broken unsubscribe link is a legal problem, not a cosmetic one.

If the old site offered a lead magnet, a PDF or discount in exchange for an email, recreate that automation too. It is usually the highest-converting signup source and the easiest to forget.

The welcome sequence is your best employee

If you set up one automation, make it a welcome sequence: two or three emails in the first week after signup that introduce you, deliver the promised lead magnet and point to your best content or offer. It runs forever without maintenance and consistently outperforms irregular newsletters. When Convert2WP handles your site conversion, the signup forms and their placement are part of the picture, so the email machinery reconnects cleanly to your new WordPress site from day one.
