What is Constant Contact?

Constant Contact is an email service provider (ESP) that handles sending infrastructure, IP reputation management, and delivery feedback for email campaigns, transactional messages, or both. Their sending reputation and your domain's authentication configuration are the two primary drivers of inbox placement when using Constant Contact.

To send as your custom domain with DMARC alignment, configure authentication through Constant Contact's domain verification — adding DNS records they provide for DKIM. Without domain verification, emails are sent from Constant Contact's domain and won't align with your From domain for DMARC.

How It Works

When you send through Constant Contact, messages leave via their SMTP servers or API. The receiving server sees Constant Contact's sending IPs in the Received headers. For your domain to pass DMARC, you must configure Constant Contact's DKIM keys and SPF include: in your DNS. Without this, email sent through Constant Contact fails authentication for your domain.

Constant Contact provides automatic bounce management, unsubscribe processing, and basic list segmentation. They handle underlying infrastructure and IP reputation management for shared senders.

Why It Matters

Your ESP affects deliverability through their shared IP pool quality, feedback loops and bounce handling, and ease of authentication configuration. Constant Contact's ease of use and template library are its primary strengths for non-technical users. Deliverability is competitive for well-maintained lists.

Regardless of ESP, the fundamentals are yours to control: domain authentication, list hygiene, engagement rates, and complaint rates have more long-term deliverability impact than the ESP choice itself.
