Question 1

Is there a contact limit on mailtani?

Accepted Answer

No. mailtani has no contact limits at any tier. Import 100 contacts or 100,000 — the price is the same one-time €89 payment. Mailchimp charges €65/month for 5,000 contacts, €130/month for 10,000, and €339/month for 50,000. With mailtani, your list can grow without your bill growing.

Question 2

Can I import contacts with custom fields from a CSV?

Accepted Answer

Yes — upload any CSV and mailtani maps each column to a contact field. Standard fields (first_name, last_name, email, company) are recognised automatically. Any other column becomes a custom field that you can use as a personalisation variable in campaigns and sequences, or as a segmentation filter. There's no limit on the number of custom fields per contact.

Question 3

How does mailtani handle duplicate contacts on import?

Accepted Answer

mailtani deduplicates by email address. If you import a contact whose email already exists in your database, the existing record is updated with any new field values from the CSV — not duplicated. This means re-importing an updated list is safe: contacts won't be doubled up and counts won't be inflated.

Question 4

What happens to contacts when they unsubscribe?

Accepted Answer

Unsubscribed contacts are immediately added to your global suppression list and excluded from all future sends — sequences, broadcasts, and any future CSV imports. The contact record still exists in your database so you retain the history. If you re-upload them in a CSV later, they remain suppressed automatically — no manual exclusion needed.

Question 5

Can I segment contacts by engagement activity like opens and clicks?

Accepted Answer

Yes — you can build segments based on: opened (in the last N days), clicked, replied, bounced, unsubscribed, or never-opened. For example: "contacts who opened in the last 30 days but never clicked" for re-engagement campaigns, or "contacts who haven't opened in 90 days" for sunset suppression. Combine filters with AND/OR logic for precise targeting.

Question 6

How do I keep my contact list clean over time?

Accepted Answer

mailtani handles most cleaning automatically: hard bounces are suppressed after each send, spam complaints are suppressed, and unsubscribes are immediate. For ongoing hygiene, you can use engagement-based segmentation to identify and suppress low-engagement contacts — contacts who haven't opened in 6+ months are a deliverability risk and are better suppressed proactively.

Question 7

Can I export my contact list from mailtani?

Accepted Answer

Yes — your full contact list can be exported as a CSV at any time, including all standard and custom fields, tags, engagement data, and suppression status. Your data is always portable — you're never locked in.

Question 8

What are the embed options for subscribe forms?

Accepted Answer

Each subscribe form gives you three deployment options: an inline form you embed directly into your page using a script tag, a popup button that opens the form in an overlay when clicked, and a hosted signup page at a mailtani URL you can link to from anywhere. All three options collect submissions into the same list and support the same custom fields, verification settings, and branding.

Question 9

What is double opt-in and how does it work in mailtani?

Accepted Answer

Double opt-in means a subscriber confirms their email address before being added to your list — reducing fake signups and improving list quality. In mailtani, you enable it by turning on email verification in the form settings and choosing "email verification link." When someone submits the form, they receive an email with a confirmation link. Clicking it verifies their address and adds them to your list. Only verified contacts are enrolled in sequences or flows — unverified submissions are held separately.
