A 90-day email and SMS marketing plan for Shopify

Use the first month to make the foundation dependable

Review sender identity, authentication, audience permissions, exclusions, and customer data quality. Test a reusable email template on mobile and verify personalization fallbacks. Confirm that the signup promise and first welcome message agree.

Choose a small set of Sendvio journeys that fit the store, such as welcome and abandoned checkout. Write down entry conditions, timing, and exits before activation. Use controlled scenarios to check purchases and opt-outs during delays. Keep the first campaign audience understandable and modest enough to review carefully.

End the first month with a small, working system

Choose an owner for audience data, one for content and offers, and one for launch approval; in a small team, one person may hold several roles. Set aside time for testing and customer questions, not just writing. A plan that fills every hour with production leaves no capacity to fix what the tests reveal.

Create a baseline using measures you can define consistently: eligible audience size, delivery outcomes, unique purchasers or another chosen conversion measure, campaign costs, and relevant negative feedback. Record the period and any limitations. You need a starting point to judge improvement, but you do not need a complicated dashboard before sending one useful message.

The first month's deliverables should be tangible: a verified sender setup, a dependable signup-to-welcome route, a tested template, and a small number of approved journeys. If permission or offer behavior remains unreliable, use the next period to fix it rather than adding more channels because the calendar says month two has begun.

Use the second month to improve relevance

Build a few actionable segments from reliable purchase and preference data. Give new subscribers, first-time buyers, and repeat customers different help when their needs differ. Add a useful purchase follow-up or reorder journey only where the product cycle supports it.

Review the combined message load across campaigns and automations. If SMS belongs in the plan, establish its specific role, permission requirements, timing, and cost. Do not duplicate every email as a text. Develop content from real support questions so the calendar offers value between promotions.

Give the second month one customer problem to solve

Choose a recurring gap supported by evidence, such as customers struggling to identify a refill or new subscribers misunderstanding the product range. Build the relevant content and audience around that problem. This keeps segmentation connected to a useful message instead of creating many groups with no clear purpose.

If SMS is appropriate, define the specific role it adds and test permission, timing, destination requirements, and segment cost. An email guide and a short availability alert can serve different needs. Duplicating every campaign in both channels increases contact pressure without necessarily adding information.

Keep a weekly review of what shipped, what customers asked, and what needs correction. Limit concurrent experiments and major journey changes to what the team can interpret. If several things change at once, it becomes difficult to learn which adjustment helped or caused a problem.

Use decision gates instead of a rigid launch calendar

Before expanding an audience, confirm that the existing group receives accurate messages and that delivery or complaint issues have been investigated. Before adding a journey, confirm that its data, eligibility, content, and exit conditions can be tested. Before adding a language, confirm that the offer and destination can be maintained in that version. These gates keep growth connected to readiness.

For a small team, one dependable improvement per week can be more useful than several unfinished launches. Rank work by customer impact and the effort required: a broken checkout link comes before a decorative template refresh, and a missing purchase exclusion comes before another promotional reminder. Keep a short backlog with an owner and a clear completion condition.

During the final month, choose an experiment that can change a real decision. If the audience is too small for a reliable comparison on purchases, do not manufacture certainty from a few orders. Use the period to improve measurement, gather customer questions, or test a more immediate usability issue while recording the limits of what the evidence can establish.

The next ninety-day plan should begin from those findings rather than restart the same checklist. Carry forward the working foundations, resolve the most consequential uncertainty, and add complexity only when it helps the customer or the team's decision. A maintainable program has fewer unexplained messages and a clearer reason for the ones that remain.

Use the third month to learn systematically

Choose one consequential question for a controlled comparison. Keep the audience and reporting definitions consistent, and record uncertainty when the sample is small. Review orders, costs, negative feedback, and relevant retention outcomes rather than declaring success from opens alone.

Audit the live journeys for outdated offers and conflicting messages. Document the best templates, prompts, and review steps so another team member can repeat the process. End the period with a short list of what to keep, what to fix, and what to test next. A strong ninety-day result is a clearer, more reliable customer experience and a team that knows why its next message deserves to be sent.

At the end of the period, prepare a one-page decision record. Keep the journeys and content that remain useful, fix the highest-impact unresolved issue, and choose one next learning question. Compare results with the baseline using the same definitions and acknowledge changes in stock, pricing, season, or audience that affect interpretation.

Do not judge the plan solely by whether every proposed campaign launched. A broken promise removed, a reliable exclusion added, or a clearer product explanation can be a meaningful improvement even before longer-term repeat behavior is measurable. The program should finish with a sustainable rhythm and a team able to explain why each active message belongs there.
