Digital Otters helps US ecommerce, B2B and service businesses turn permission-based email and SMS into acquisition, conversion and retention programs. Strategy, segmentation, campaigns, lifecycle flows, templates, deliverability, consent operations and revenue reporting are managed as one system.
Email and SMS marketing services run the owned channels — campaign strategy, flows, segmentation, deliverability and compliance — where the audience costs nothing to reach again. In 2026 deliverability is the gating skill: Google and Yahoo enforce authentication (SPF, DKIM, DMARC) and spam-rate thresholds for bulk senders, and a program that ignores them simply stops arriving.
Direct definition: Digital Otters is an email and SMS marketing agency providing strategy, segmentation, campaigns, lifecycle journeys, templates, sender authentication, deliverability, consent management, testing and performance reporting.
The exact scope follows your current systems, commercial objective and who is implementing.
Audience, permission, message roles, campaign calendar, lifecycle journeys, frequency and commercial goals — agreed before anything is built.
Domain authentication, list-quality controls, unsubscribe paths, stream separation and monitoring, configured to the agreed scope.
Segmentation, copy, design, QA, sends, testing, reporting and improvement driven by business outcomes rather than send volume.
Four controls decide whether a bulk program keeps arriving. Select one to see the requirement, what failure looks like, and the work that fixes it.
SPF, DKIM and DMARC let receiving systems verify authorised sending and domain alignment. Provider requirements vary by sender type and volume, and bulk senders are held to the strictest version.
Google Postmaster Tools, DMARC aggregate reports and platform sending logs.
Mailbox providers hold bulk senders to a user-reported spam rate under roughly 0.3%. The number is a ceiling to stay well beneath, not a target to approach.
Google Postmaster Tools spam-rate reporting and platform complaint dashboards.
Bulk senders must support one-click unsubscribe in the message header and honour it quickly. SMS programs must honour STOP and equivalent opt-out keywords.
Seed-list testing, platform suppression logs and opt-out latency checks.
Promotional, lifecycle and transactional mail have different permission and delivery requirements. Mixing them puts receipts and password resets behind promotional complaints.
Platform list-health reports, bounce classification and per-stream reputation monitoring.
Since the major mailbox providers began enforcing sender requirements, deliverability moved from hygiene to strategy: bulk senders must authenticate with SPF, DKIM and DMARC, support one-click unsubscribe, and keep user-reported spam under roughly 0.3% — or watch messages quietly stop arriving. Our programs treat those thresholds as hard limits: authentication verified before the first send, engagement-based sunsetting so unengaged addresses stop dragging the domain, and list growth that never buys its way into a spam trap. SMS runs stricter still, because regulators and carriers both punish carelessness and the channel's intimacy is exactly what makes it convert.
An email address or phone number is not unlimited permission. Expectations, message type, frequency, sender identity and withdrawal must be clear. These five patterns cause most of the damage we are asked to repair.
Get a permission reviewA purchased, transferred or operational list may not be valid for promotional communication. Having an address is not the same as having permission to sell to it.
Mailbox and messaging providers, laws and customers all treat them differently. One promotional complaint can then threaten a receipt or a password reset.
Gmail and Yahoo bulk-sender requirements emphasise authentication and easy unsubscribe, and SMS programs must honour opt-out signals. Friction converts exits into complaints.
Inactive or unhappy recipients increase complaints and drag down sending reputation for everyone else on the domain, including your best customers.
Privacy features made opens unreliable. Clicks, replies, purchases and downstream actions are what should decide segmentation, sunsetting and content.

We would rather name a constraint before a proposal than disguise it with send volume. If the right-hand panel describes you, the honest answer is not yet.
We scope platforms, contacts, markets, campaigns, automation, templates, languages, authentication, SMS sender types, consent work, testing and reporting. Message, contact, number, registration and platform fees remain separate.
Recurring campaign production: segmentation, copy, design, QA, sends and reporting on an agreed calendar.

You receive a tailored US-dollar proposal with deliverables, responsibilities, milestones, assumptions and support boundaries — plus the order we would run the work in if budget has to be staged.

Yes, subject to market, sender registration, consent, platform and legal requirements. The client remains responsible for obtaining legal advice.
SPF, DKIM and DMARC help receiving systems verify authorised sending and domain alignment. Provider requirements vary by sender type and volume.
No. Deliverability depends on authentication, reputation, list quality, recipient behavior, content and mailbox-provider decisions.
We map consent source and message type, store preferences, maintain suppression and ensure unsubscribe or STOP handling is connected to the sending system.
They can have different permission, content and delivery requirements. Separating streams can protect critical transactional communication.
We use delivery, complaints, unsubscribes, clicks, replies, conversion, revenue and lifecycle progression. Opens are interpreted cautiously.
Pricing depends on list size, sending frequency, number of campaigns and flows, copy and design requirements, segmentation, deliverability work, platform complexity and reporting. Platform and message fees are separate.
Yes. Digital Otters can work with Klaviyo, HubSpot and suitable email, SMS or CRM platforms after reviewing access, features, integrations and sender requirements.
We can implement the client's approved consent, identification, unsubscribe, STOP handling and suppression requirements, but we do not provide legal advice. The client should confirm applicable requirements with qualified counsel.
