The IGSendMail Blog

    Practical, no-fluff email marketing writing for operators who care about open rates, click-through, deliverability, and real revenue. Every post is written by people who actually run programs at scale, not freelancers chasing keywords.

    Whether you're sending your first welcome series or migrating a million-subscriber list off legacy ESPs, you'll find guidance grounded in shipped campaigns, A/B test results, and conversations with deliverability engineers at the major mailbox providers. We update older posts when standards change so you never end up implementing advice that became obsolete two years ago.

    What you'll find here

    Deliverability deep dives

    SPF, DKIM, DMARC, BIMI, postmaster tools, sender reputation, warming new IPs, recovering from blacklists, and decoding bounce codes. The technical layer most marketers ignore until it breaks.

    Automation playbooks

    Welcome series, abandoned cart sequences, browse abandonment, post-purchase, win-back, and lifecycle journeys. Each playbook ships with timing recommendations, copy frameworks, and benchmark conversion rates.

    Growth and list building

    Lead magnets, popup conversion strategy, double opt-in mechanics, list hygiene, segmentation models, and how to grow a list ethically without buying contacts that will torch your reputation.

    Strategy and product updates

    Industry analysis, regulatory changes (GDPR, CAN-SPAM, Apple MPP, Yahoo and Gmail bulk sender requirements), and what's shipping inside IGSendMail. The why behind the what.
