Building Your First Email Campaign

An email campaign is a targeted batch of marketing emails sent to a defined audience with a specific goal — a promotion, a newsletter, a re-engagement effort, or an announcement. This article walks you through building and sending your first campaign using MigoSMTP, from audience preparation to post-send analysis.

Before You Send — Pre-Campaign Checklist

Step 1 — Define Your Campaign Goal

Every campaign should have a single, clear goal. Mixing goals in one email dilutes your message and confuses recipients. Define yours before writing a single word:

• Drive traffic: Get recipients to click through to your website or landing page.
• Generate sales: Promote a specific product, offer, or discount.
• Build awareness: Introduce a new feature, product, or brand update.
• Re-engage inactive subscribers: Win back lapsed readers before removing them from your list.
• Gather feedback: Drive survey completions or NPS responses.

Step 2 — Prepare Your Recipient List

Your recipient list is the most important factor in campaign success. A well-maintained list of genuinely interested recipients consistently outperforms a large, low-quality list.

List preparation steps:

1. Segment your audience — do not send the same email to everyone. Group recipients by interest, purchase history, location, or engagement level and tailor the content to each segment.
2. Remove hard bounces — check your previous delivery reports and remove any addresses that resulted in a hard bounce. Sending to known-bad addresses hurts your reputation.
3. Check suppression list — MigoSMTP automatically skips suppressed addresses, but review your suppression list to confirm it is current before a major send.
4. Validate email format — run your list through a format validation check to catch obvious typos (e.g. user@gmial.com).

Step 3 — Create Your Email Template

A well-structured marketing email contains the following elements:

Step 4 — Send via MigoSMTP API (Bulk Sending)

For sending a campaign to a list of recipients, use the bulk email endpoint:

POST https://api.migosmtp.com/v1/email/send/bulk
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json

{
  "from":     "newsletter@yourcompany.com",
  "subject":  "Our biggest sale of the year starts now 🎉",
  "html":     "<html>...your template...</html>",
  "text":     "Our biggest sale of the year starts now.",
  "recipients": [
    { "to": "alice@example.com", "variables": { "first_name": "Alice" } },
    { "to": "bob@example.com",   "variables": { "first_name": "Bob"   } }
  ],
  "track_opens":  true,
  "track_clicks": true,
  "tags": ["campaign:summer-sale-2026"]
}

Step 5 — Scheduling Your Campaign

The time you send a marketing email significantly affects open rates. General benchmarks for India-focused campaigns:

Step 6 — Monitor Campaign Results

After sending, monitor results in Reports → Delivery Reports. Filter by the tag you added to the campaign (e.g. campaign:summer-sale-2026) to isolate your campaign metrics:

• Watch the delivery rate for the first hour — a sudden drop indicates a deliverability issue.
• Monitor the bounce rate — if it exceeds 5%, pause the campaign and clean the list before resuming.
• Track opens and clicks in the first 24 hours — most engagement happens in this window.
• Check spam complaints — even one or two complaints from a small send is a serious signal to investigate.
