Moving from Constant Contact to Meser10

Keep your list, your designs and your unsubscribes. This is how you export them from Constant Contact and bring them into Meser10, one step at a time.

Why organizations move to Meser10

Step 1: Export your contacts from Constant Contact

1. Go to Contacts and select your contacts. To select everyone, tick one contact and click Select all contacts.
2. Click Actions, then Export selection.
3. Choose the fields you want and click Export.
4. On the import and export activity page, click Download CSV or Download Excel.

Filter by email status (unsubscribed) and export those contacts as a separate file, so you can bring them in as removed contacts in step 4. Constant Contact includes permission status in the export only when Advanced Email Permissions is turned on before you export.

Step 2: Bring over your designs

The easiest way is the campaign's permanent link: Meser10 pulls the content from the address into the editor. If you built the email in Constant Contact's code editor, you can also copy the HTML and paste it. The editor guide covers the rest.

Step 3: Import the file into Meser10

1. Open a Meser10 account, or log in to your existing one.
2. Import contacts: create a new list and upload the file (Excel or CSV).
3. Match each column to a field: email, first name, last name, mobile phone. Leave columns you do not need unmatched.

Duplicate addresses are imported once. Numbers matched to the mobile phone field let you send SMS to the same list.

Step 4: Import your unsubscribes as removed

People who unsubscribed in Constant Contact should not hear from you after the move either. Import the unsubscribe file as a separate file, and those contacts get the removed status: they receive no mail and do not count toward your package. See contact statuses.

Do not import bounced addresses at all. If you are unsure about the quality of the list, run list cleaning before the first mailing.

Step 5: Before your first mailing

1. Set up your sending domain (SPF, DKIM and DMARC). Support sends you the DNS records to add at your domain registrar.
2. A new domain should be warmed up gradually, and our team does it for you. Warm-up on your own list is included at no extra cost: we split your existing contacts into groups by engagement and raise the volume step by step. A faster warm-up with our seed mailboxes, which open, reply and behave like real readers, is a paid add-on: how domain warming works.
3. Send a test to yourself first, and only then to the whole list: preview and test.

New customers can get a one-time welcome gift of 250 emails and 50 SMS: after signing up, ask support. Prices for every package are on the pricing page.
